Raspberry Pi 4 Review: The New Gold Standard for Single-Board Computing
头头体育滚球官网 www.yihuifanyi.com Raspberry Pi has long been the gold standard for inexpensive single-board computing, powering everything from robots to smart home devices to digital kiosks. The long-anticipated Raspberry Pi 4 takes Pi to another level, with performance that's good enough to use in a pinch as a desktop PC, plus the ability to output 4K video at 60 Hz or power dual monitors.
The best Raspberry Pi yet is faster and more functional than any of its predecessors, without raising the price.
Raspberry Pi 4
The best Raspberry Pi yet is faster and more functional than any of its predecessors, without raising the price.
For the same $35 starting price as prior models, you get speeds that are two to four times faster, support for USB 3 and true Gigabit Ethernet. Perhaps more importantly, there is a $45 Raspberry Pi 4 with 2GB of RAM and a $55 unit with 4GB, four times more than any previous Pi has had. Makers and hobbyists should add the Raspberry Pi 4 to their arsenals, and tech enthusiasts who've never used a Pi before now have even more reasons to buy one.

We had an opportunity to get early access to the Raspberry Pi 4 B, the full name of the first Pi 4 model, and were able to test a board with the full 4GB of RAM. What we saw is a full-fledged mini computer that's packed with potential. We're particularly excited about the possibilities for inference, particularly object and sound detection.
Backward Compatibility
It's important to note that, even a couple of months after launch, some important Raspberry Pi software doesn't yet work on the Pi 4. To run Pi 4, you'll need to download a brand new build of the Raspbian OS,?Raspbian Buster. And not everything runs in Buster yet. During testing, we found numerous Python libraries or other required packages that weren't compatible with the new OS.
Game Emulation or Lack Thereof
Retropie, the very popular gaming emulator software, does not officially support the Raspberry Pi 4. We did find a workaround that lets you?run Retropie on the Raspberry Pi 4, but right now it's a kludge that doesn't necessarily work well. You can also download a beta version of Lakka, another emulation platform, but it too is not a final, fully working build. Developers have said that they are working on a Pi 4-compatible version and will have one soon, but if you're reading this today and need to build an arcade machine in the near future, you might want to get an older model.?
Key Differences
The table below shows a key specs comparison between the Raspberry Pi 4 B, the first an only Pi 4 model, and the Raspberry Pi 3B+, the fastest version of the Pi 3.

The most important new features are the faster processor and GPU, more and faster RAM, the addition of USB 3 ports, dual micro HDMI ports instead of a single HDMI connection and support for 4K output. The higher bus speed that enables USB 3 support also allows the on-board Ethernet port to support true Gigabit connections (125 MBps) where the last-gen models had a theoretical maximum of just 41 MBps. The microSD card slot is also twice as fast, offering a theoretical maximum of 50 MBps versus 25 MBps on the 3B+.
Because the new SoC needs more power, the Raspberry Pi 4 B charges over?USB Type-C?instead of micro USB. It also requires a power adapter that can deliver at least 3 amps of power and 5 volts, though you may be able to get away with 2.5 amps if you don't attach many peripherals to the USB ports. Putting aside the power needs, USB Type-C connectors are reversible, which makes them much easier for kids (and adults) to plug in.
After we first published this review, we found out that some USB Type-C cables don't work with the Raspberry Pi 4. Those cables that are "electronically marked" will see the Pi 4 as a USB audio device and not provide power. Only USB-C to USB-C cables can be electronically marked and you only find this on cables that operate at 5 Gbps or higher. In our tests, we found?11 low-cost USB-C cables that work with the Raspberry Pi 4?and only found a few cables, all USB 3.1, that did not. If you buy Raspberry Pi's official Pi 4 charger, which comes with a cable, you also won't have a problem.? The Pi foundation says it will fix the problem on future builds, but it can't be solved via a firmware update.?
At 3.5 x 2.3 x 0.76 inches (88 x 58 x 19.5 mm)? and 0.1 pounds (46 grams), the Pi 4 is thin enough to fit in your pocket and light enough to carry anywhere. The board is durable enough to probably survive rolling around in your bag, but we recommend sticking it in something protective, mostly to protect the pins. However, during testing, I always used the board bare on my desk and I carried it back and forth between work and home many times by simply putting it in a cardboard box with no padding or static bag.
Unfortunately, if you want a case, you can't use one that's been designed for any previous Raspberry Pi. The Raspberry Pi 3 B / 3 B+ have almost the same dimensions, but the port layout has changed just enough to make the Pi 4 B incompatible. Where prior Pis had a single, full-size HDMI port, the dual micro HDMI connectors on the Pi 4 jut out more and so don't line up with the holes on anything that was designed for the Pi 3 B. We really like the Pimoroni Pibow, a $10 / £8.50 case that looks really good and doesn't cover over the GPIO pins.
The Raspberry Pi 4 covers more than just the basics when it comes to ports. The right side has four USB Type-A connections, two of which are USB 3.0. There's also a full-size, Gigabit Ethernet port for wired connections there. The bottom edge has a 3.5mm audio jack, two micro HDMI ports and the USB Type-C charging port. On the left side, you'll find the microSD card reader.
And on the top surface of the board, you'll see ribbon connectors for the Camera Serial Interface (CSI) and Display Serial Interface (DSI), which provide dedicated connections to Raspberry Pi's own camera and screen (or compatible accessories). Of course, you can connect a camera to a USB port as well and there are a couple of more common ways, including the micro HDMI ports, to output to a screen.
New CPU, RAM
The Raspberry Pi 4 has similar design and dimensions to its predecessors, but it's an all-new platform, powered by a new processor, the Broadcom BCM2711B0. Since the first Pi in 2012, all? Pis have used 40nm SoCs, but this new chip is based on a 28nm process and, instead of the older Cortex-A53 microarchitecture, it uses Cortex-A72. The BCM2711B0 in the Raspberry Pi 4 has four cores and is clocked at 1.5 GHz, which at first blush, doesn't seem much quicker than the quad-core, 1.4 GHz BCM2837B0 in the Raspberry Pi 3B+.
However, Cortex A72 has 15-instruction pipeline depth, compared to just 8 on the older model, and it also provides out-of-order execution so it's not waiting for the output of one process to start on another. So, even at the same clock speed (and the BCM2711B0 is based on a smaller process node), Cortex-A72 processors will be significantly faster and use more power than their A53-powered ancestors.
For example, on the Linpack benchmark, which measures overall compute power, the Pi 4 absolutely whooped the Pi 3 B+ in all three tests. On the all-important single precision (SP) test, the Pi 4, scored 925 as compared to the 3 B+'s mark of 224, a boost of 413 percent.
On the Sysbench CPU test, the Pi 4 B was capable of performing 394 events per second as compared to 263 for the Pi 3 B+. That's a difference of 50 percent.
The RAM is also quite a bit quicker, going from 1GB of DDR2 RAM operating on the Pi 3B+ to up to 4GB of DDR4 RAM. In addition to the increased bandwidth, having more memory is a huge deal, particularly for web surfing.
The Pi 4's RAM returned read and write rates of 4,130 and 4,427 Mbps, respectively. That's 51 percent and 54 percent better than the 3 B+.
Both the CPU and the RAM are implicated when you do file compression. When zipping a file in multithreaded mode, the Pi 4 B is 37 percent quicker than its predecessor, but it's far stronger in single-threaded, eclipsing the 3 B+ by 60 percent.
New GPU, Faster Graphics Performance
The GPU is getting a nice boost too. It moves from a Broadcom VideoCore IV that operated at a core clock speed of 400 MHz to a VideoCore VI that's set at 500 MHz. The new architecture allows it to output to a display at up to 4K resolution with a rate of 60 fps or to support dual monitors at up to 4K 30 Hz.
While we wish we could have tried some of the more resource-intensive emulators in Retropie in time for this review, there wasn't a Pi 4-compatible version at launch. However, the OpenArena Benchmark, which measures frame rates in a game that's a a clone of Quake III Arena, did run.
At 720p resolution, the Pi 4 was the only Raspberry Pi capable of delivering smooth frame rates. Yes, you can play on the Pi 3, 3 A+ or 3 B+, but all three deliver rates between 27 and 28 fps as compared to 41.4 fps on? the Pi 4.
Storage Performance
No matter how fast your processor, RAM and GPU are, if your storage is slow, everyday tasks like opening apps and files will be laggy. Like all Raspberry Pis, the 4 B's primary storage device is its microSD card reader, which is convenient but a bit constrained. According to the Pi Foundation, the 4 B has a top transfer rate of 50 MBps, which is double the speed of the reader on the 3 B+. There's no known limit on capacity.
Our benchmarks, which were conducted with a Samsung EVO Plus microSD XC Class 10 card, show less impressive rates than the theoretical maximums. The Pi 4 B returned sequential read / write rates of 45.7 and 27.7 MBps, while the 3 B+ trailed at 22.8 and 17.5 MBps. Keep in mind that the card is rated for 100 MBps reads and 60 MBps writes.?
If you have a speedy USB Flash drive or an external SSD, you can get far better storage performance out of the Pi 4 B. The Pi 4 B is the first with USB 3 ports, which have a maximum, theoretical bandwidth of 625 MBps. To find out how this works in real-life, we wrote a separate article where we attached an?external SSD to a Raspberry Pi 4 B.? You'll find full results in the article, but what we found was impressive.
Using a?Western Digital Blue SSD?in a USB to M.2 enclosure, we saw transfer rates that were 2 to 13x times faster than the microSD card. And applications definitely opened a lot faster with the SSD attached. Unfortunately, a regular USB Flash drive, was often slower than the microSD card.?
However, it's important to note that, at present, the Pi 4 firmware doesn't allow you to boot off an external drive so the best that you can do is run all of your programs, including the majority of the OS, off of an SSD while leaving the boot partition on a microSD card. A firmware update should fix this in the next few weeks, but for now, we have an article explaining how to?run your Raspberry Pi 4's software from an SSD.
Fast USB 3 ports are about more than just storage. You can use other high-bandwidth peripherals like Google's Coral USB Accelerator, which helps with artificial intelligence tasks.
Networking Performance
The Raspberry Pi 4 has the same 802.11ac Wi-Fi as its direct predecessor, but it throws in Bluetooth 5.0 support, an improvement over the Bluetooth 4 on prior models. More importantly, the Ethernet port now has more bandwidth, which allows it to offer a full gigabit of throughput where prior models could only achieve about 330 megabits.
In testing, the PI 4 B's Ethernet port achieved 943 Mbps, which blows away the other Raspberry Pis. In fact, in a throughput test, the Pi 4 B got 943 Mbps (close to the 1,000 Mbps maximum). That's nearly five times as many as the Pi 3B+, which only got 237 Mbps.
Both the old and new Raspberry Pi have 802.11ac Wi-Fi that can run on 2.4 GHz or 5-GHz bands. So we didn't expect to see much difference in performance here. But the 5-GHz throughput is noticeably higher for the Pi 4, returning a rate of 114 Mbps, compared to 97 Mbps on the Pi 3 B+, a decent 18 percent improvement.
Power and Heat
With a more power-hungry processor and the need for at least a 5-volt, 3-amp power adapter, the Pi 4 should be expected to consume more power than its predecessors.
At idle, the Pi 4 B draws 3.4 watts, which is just 17 percent more than the 3 B+. Under load, that number jumps to 7.6 watts, but that's still only 19 percent more juice than its direct predecessor. If you want the lowest-power Pi, performance be damned, then go for the Pi Zero W, which consumes a mere 0.8 watts at idle and 1.6 watts under load.
Yes, this board gets warm, warmer than its predecessor. Thermal images mirror what we experienced; the areas of the board near the CPU get really warm, not just the top of the processor itself. The Pi 4 board reaches a toasty 74.5 degrees Celsius (166 degrees Fahrenheit). That's not enough for a serious burn, but kids especially should be sure to pick up the Pi by its sides only. The top surface of the Pi 3 B+ is much cooler, maxing out at 62.5 degrees Celsius (144.6 degrees Fahrenheit).

As with any modern computer,? if you push the system too hard and the CPU or GPU get too hot, the computer will throttle down to avoid damage.
While running a CPU-intensive workload for 10 minutes, the processor hit 81 degrees and began throttling down from 1.5 to 1 GHz after 3 minutes. However, the system kept bringing itself back to the full 1.5 GHz when it dipped down to around 80 degrees, but then it would get warm again and go down to 1 GHz. If you want to have better sustained performance under load, consider getting an active cooler for the Raspberry Pi 4 or, at the very least, attach a passive heat sink.
GPIO Pins
The real star of the show on any Raspberry Pi is its set of 40 GPIO (General Input / Output) pins. The pin count and layout remains unchanged from prior models, going back to the Raspberry Pi 2, so any "hats," sensors or LED screens that were made to attach to a Pi 2 or 3 will be compatible.

However, the Raspberry Pi 4 has added a few new capabilities to some of the pins. For hardcore makers who are wiring up a variety of peripherals, the GPIO pins now support four additional I2C, SPI and UART connections. So, if your sensors or peripherals require any of these interfaces, you now have a lot more of them.
Below, you'll find a new GPIO pinout, with the added capabilities of the Pi 4. To learn more about what each pin does, checkout our Raspberry Pi 4 GPIO pinout article.

The speed and responsiveness of the GPIO pins is also much faster on the Raspberry Pi 4, likely due to its faster processor. Our test uses the gpiozero Python library to toggle pins on and off continuously and measures the rate at which they switch. The Pi 4 achieved a speed of 50.8 KHz, compared to just 16.1 on the Pi 3 B+. That's an improvement of 215%.
Using the Raspberry Pi 4 as a PC
One of the goals of the Raspberry Pi 4 is to be a capable PC that anyone can use for surfing the web, doing light productivity work or even playing very basic games. In order to test this use case, I spent several hours doing my everyday work on the device and I even wrote portions of this review using it.
I really liked being able to output to dual monitors, something I do everyday at both work and home. And, since much of my daily work routine these days takes place in a web browser, I had no problem writing, editing and researching articles using Chromium. Even with 15 tabs open, switching between them was smooth and I had not maxed out the 4GB of on-board RAM.
And while I wouldn't want to use it every day, GIMP provides a decent way to edit still images. If I wanted to crunch spreadsheets or compose documents outside of Google Docs, Libre Office more than fits the bill.
My biggest problems involved video playback. If I wanted to watch a YouTube video, I had to keep it in a window, because even in 480p resolution, it was jerky at full screen. The other task I'd like to perform is playing retro games, but as of this writing, the Retropie package of emulators doesn't work with Pi 4. I was able to install and play Quake Arena, however.
Keep in mind that the Raspberry Pi 4 works with a few different operating systems, but the best-supported one is Raspbian, a flavor of Linux that has a small learning curve for newbies. Users who are only looking for a low-cost web-surfing PC, without doing any tinkering, can find a Chromebook or low-end Windows laptop for $150 to $200.?
4K Output, Video Playback and Transcoding
One of the downsides of prior Raspberry Pi computers is that they can only natively output to one screen at a time, but if you like multitasking and want to use a Pi for productivity, you really want that second screen. The Raspberry Pi 4 has dual micro HDMI ports that can each connect to a separate monitor or TV and can operate at up to 4K (3840 x 2160) resolution. If you have multiple 4K monitors, you have a choice: you can either run each screen at a somewhat-sluggish 30 Hz or, you can enable 4K mode in the settings menu, which jacks up the voltage a little so you can run one monitor at 4K 60 Hz and another at up to 1080p.
During extensive hands-on testing, I found that, while the 4K at 30 Hz is tolerable, little things like the movement of the mouse pointer are a bit sluggish. If you have a 4K screen, you're definitely better off going for the 60 Hz mode, but note that the added voltage may also cause your CPU to get hot and throttle more easily.
While surfing the web, looking at still images and just enjoying all the extra screen real estate of 4K is great, video playback is the Raspberry Pi 4's Achille's heel, at least as of this writing. Whether we were attempting to stream a 4K video or use a downloaded file, we never got a smooth, workable 4K experience, either in Raspbian Buster or LibreElec, an OS that runs the Kodi media player. Several H.264 encoded videos, including Tears of Steel, did not play at all or showed as a jumble of colors. Even the sample jelly fish videos that the folks at Kodi recommended for my testing appeared as still pictures with no movement. Clearly, there's a lot of optimization that still needs to be done both on the OS and software side to make the Raspberry Pi 4 capable of playing 4K video.
Unfortunately, even streaming 1080p YouTube videos is a challenge at this point. Running at 1080p resolution, full screen video trailer for Stranger Things showed obvious jerkiness. However, the playback was smooth when I watched the same clip in a smaller window. The same problem occurred, even when I dropped the stream's resolution down to 480p.
Playing offline 1080p videos works well, provided your screen is at 1920 x 1080 or lower resolution. A downloaded trailer of Avenger's Endgame was perfectly smooth when I watched it using the VLC player.
The Raspberry Pi 4 won't replace anyone's MacBook Pro or Dell XPS 13 creative workstation, but it can transcode videos for you, if you're patient. It took the Raspberry Pi 4 48 seconds to transcode a very short H.264 encoded clip to NTSC DV format using FFmpeg. That's much less time than the Pi 3 B+, which finished in 108 seconds, but if you're converting a whole movie, you'll probably need to walk away from your Pi for a while and then come back.
Web Surfing
The web surfing experience on the Raspberry Pi 4 is noticeably much smoother than on any of its predecessors. The faster processor helps, but so does having more than 1GB of RAM. Keeping my eye on Gnome System Monitor, I noticed that, even with just one or two tabs open, I was using more than 1GB of RAM. However, on the Pi 4 with 4GB of RAM, I had no problem running over 15 tabs at once, switching back and forth between them.
While web pages don't render as quickly as on my modern Core i7-powered laptop with Windows 10, the Pi 4 provides a very solid web browsing experience. I had no problems using my Google suite apps, including Gmail, Google Sheets and Google docs.
On Jetstream 1.1, a synthetic browsing benchmark that measures Javasript processing and page rendering, the Pi 4 trounced the Pi 3B+, 42.5 to 17.1? That's an improvement of 148%, but the Pi still isn't quite as powerful as a low-end, Intel-powered Chromebook like the Samsung Chromebook 3, which scored 49.7. However, there are PC laptops that fared worse, including the Dell Inspiron 14 3000, which hit just 35.9.
The Speedometer 2.0 benchmark measures overall responsiveness by loading dummy web apps and then simulating a user interacting with them. A higher score on this test, in terms of runs per minute, shows that when you're actually using a web tool such as Google docs or Gmail, you should get less lag. As on Jetstream and in real-world scenarios, the Pi 4 came out comfortably ahead of its predecessor. In this case, it was 98 percent faster.
Just forget about using web sites with webGL animation on them, because they are slideshow like, at least with the current software. When I launched the webGL aquarium demo, which shows 50 fish swimming, I got a rate of just 2 fps on the Raspberry Pi 4 and a mere 1 fps on the Pi 3 B+. I guess that makes the Pi 4 twice as fast, but 2 fps is still useless.
Web Hosting
It's very easy to use set up a?Raspberry Pi web server?and this is one of the most popular use cases for the computer. In fact, at Tom's Hardware, we use a Raspberry Pi 3 B as a server on our local network that we use to host our laptop battery test. Raspberry Pi 4 promises even more robust web surfing thanks to its faster processor, greater amount of RAM and better network connectivity.
Using the Phoronix Apache Test, the Raspberry Pi 4 handled 3,983 requests per second versus 2,850 for the Pi 3 B+. That's an improvement of 40 percent, which means that you can deliver heavier web pages or serve more visitors at the same time, without lag.
Many web applications use the PHP server-side scripting language so faster processing of PHP can help a lot. On PHPBench, which measures PHP performance, the Raspberry Pi 4 B scored 101,540, more than double the Pi 3 B+'s mark of 41,351.?
A.I., Inference and Machine Learning
Perhaps the most exciting new use case for the Raspberry Pi 4 is for inference and machine learning. With the earlier Pis, you could already use a camera to do simple object detection at low frame rates, but the added performance and I/O from this new model should open up a whole new world of use cases.
To see how well the Pi 4 handles object detection, we followed the steps in this tutorial, which uses a combination of Google's TensorFlow machine learning platform and OpenCV, a programming library that's good for computer vision. After spending a good three hours compiling and installing all the software, I got the app running and watched as the webcam identified a few -- very few -- objects in my office, including sensing that I was a "person" and my chair was a "chair" with great confidence. It operated at a sluggish rate of 1.7 fps, but that's 70 percent better than the 1 fps I got when running it on the Pi 3 B+.
However, with a more optimized framework, the Pi 4 should be able to do real-time facial and object recognition. And, because it has USB 3, an accelerator like the Google Coral TPU USB dongle should have much more bandwidth to send data back to the SoC. Imagine building a home companion robot that recognizes every member of your household by face or one that helps a farmer sort cucumbers by type. Some of these workloads are possible on earlier Raspberry Pi computers, but the Pi 4 B should make them fast and accurate enough to use on a regular basis. We can't wait to see what developers and what makers do with Pi 4 and A.I.
Scikit-learn is a popular python module that enables machine learning. Performing a task in Scikit-learn was more than twice as quick on the Pi 4 B.
Compiling Code
With Linux, you sometimes have to compile programs you want to install. Several times during our testing, we had to compile software packages, including when we wanted to get an object recognition demo going.
A speedier processor and better RAM help the Raspberry Pi 4 B compile code much faster than its predecessor.? When we ran a test which compiles a Linux Kernel, the 4 B finished 33 percent faster. So, whether you're a developer who is writing your own software or just a user who wants a program that's not available as a direct download, the Pi 4 will save you time.?
Overclocking the Pi 4
We've explained how to overclock the Raspberry Pi 4 and what kind of results you get in a separate article. However, the top line is that you can easily get the 1.5 GHz CPU up to?2 GHz?and increase the frequency of the GPU from 500 to 600 MHz without missing a beat. Just make sure that you have a fan like the?Pimoroni Fan Shim.
How Much Raspberry Pi 4 RAM Do You Need?
The Raspberry Pi 4 B comes in three configurations, which are identical but for the amount of RAM. The $35 entry-level model has 1GB of RAM, the $45 unit has 2GB and the $55 SKU goes all the way to 4GB. One of the great advantages of all Raspberry Pis is that they are affordable enough to use in anything, so you need to choose wisely. If you are building a robot or other iOT device that just deals with motors and sensors, 1GB should be enough, because you aren't running a slew of apps and you don't even need the GUI.
We recommend 2GB if you're doing very light web surfing, setting up a kiosk or deploying a limited-use web server. The 4GB model is ideal for using your Pi as a PC or for more complex tasks such as A.I.
Bottom Line
The Raspberry Pi 4 represents a giant leap forward, not only for the Raspberry Pi, but for single-board computing. For the first time, it's realistic to use your Pi as a secondary or backup PC (or perhaps a kids' first PC). However, the larger real benefit will come not from folks who use Raspberry Pi 4s in lieu of x86 PCs, but from all the innovators who harness the system's enhanced performance, I/O and graphics to create new iOT devices, media servers and robots. Kids building Pi projects in school will also have a world of new learning possibilities.
If you need a Raspberry Pi computer today, though, you'll have to live with some issues that are likely to get resolved in the near future via software updates. Key apps like Retropie don't yet run Raspberry Pi 4 and video playback performance is disappointing. While it's certain that major applications will be ported to the new computer, we still don't know exactly how good video playback will get once the operating system is refined over time.
Despite these small issues , the Pi 4 stands head and shoulders above its predecessors and all the other inexpensive single board computers on the market. The main question isn't: what can the Pi 4 do for you out of the box, but what can you make with it?
Editor's Note: Some of the benchmarks in this article were performed by co-author Gareth Halfacree, who has posted his own, detailed analysis of Raspberry Pi 4 performance on Medium.

TerryLazeAny plans on comparing the atomic PI to the raspberry?
It's based on x86 so it would be much more compatible with what people need to run.
bit_userI'm pretty sure your table has the GPU specs swapped. It says the Pi 3 has a 500 MHz VidCore VI and the Pi 4 has a 400 MHz VidCore IV.
Speaking of the GPU, I'm really interested in support for OpenCL, Vulkan, and which OpenGL version it supports. Any other specs on the GPU would also be welcome!
I should add that I'm actually a bit disappointed by the OpenArena benchmark. Given how old and slow the earlier Pis' GPU was (yes, even the Pi 3 used the same GPU as the original model that launched in 2012, just clocked a bit higher), I fully expected a much bigger jump. Think about how far desktop GPUs have come in that time - since Nvidia's GeForce 600 series and AMD's HD 7000 series.
bit_userQuote:Any plans on comparing the atomic PI to the raspberry? It's based on x86 so it would be much more compatible with what people need to run. https://dlidirect.com/products/atomic-pi
Overall, I think the Pi 4 would definitely win. The Atomic's SoC was designed for cell phones, that were none too popular. The Cortex-A72 cores in the Pi 4 are a bit newer and more efficient. Also, the Atomic Pi uses single-channel DDR3L, while the Pi 4 uses DDR4L.
Of course, the Pi 4's biggest weakness remains storage. So, for I/O intensive tasks, the Atomic would still pull out some wins.
bit_userIn terms of specs, the best (sub-$100, at least) is still the ODROID N2:
LordConradIt'll be a nice change to have the support of the Raspberry Pi community AND a fast SBC to go with it. I never bought any of their previous SBCs because, for an extra $10-20, their competitors were always much better.
AllanGHQuote:Any plans on comparing the atomic PI to the raspberry
The Atomic Pi was dead before it was put up for sale....just somebody flipping old stock and system pulls from a mini-robot product. You won't be seeing support or new iterations of that platform--not from the purported manufacturer, at any rate.

I was taken in at first by all the promise and claims being made. Really glad I waited to purchase one until more detail came out.
It seems that in addition to a fairly high fail rate, there are significant problems with audio, the well known poorly dealt with power delivery, as well as issues running "heavy" OS like it was purported to be capable of.
The lack of possible future support was the final straw for me. This is a once it's gone, it's gone kind of thing. The whole thing was made for a different purpose and has connectors and functionality that, as of yet are (mostly) unknown and unable to be utilized.
Many of the reviewers stated that even though the audio and OS issues were mostly resolvable that the time spent doing so outweighed the value. By and large the consensus among many of the purchasers was to go RPi for the community, the support, and the I/O functionality.
TJ HookerThe 'Everything We Know about the Pi 4" article (from ~4 months ago) didn't age well :P
"Release Date: Not Coming in 2019"
technome79The article mentions "true Gigabit Ethernet ". What is true gigabit ethernet? And what makes other gigabit ethernet false?
TJ HookerQuote:The article mentions "true Gigabit Ethernet ". What is true gigabit ethernet? And what makes other gigabit ethernet false?
The 'gigabit' ethernet on previous models was fed by a USB 2 connection, which is not capable of providing actual gigabit speeds. The "true gigabit ethernet" now allows for actual Gb/s throughput.
AllanGHI never really did a drill-down into the specs before pre-ordering 2 of the model 4s, and it now occurs to me that I really am hoping that RPF decided to add a lucid soft power switch facility to the board.
I suppose I could actually look to see, but that would spoil the surprise. Nevertheless, if they didn't, the old method of adding a soft-power button will likely still work.
AlistairABOdroid N2 looks nice. Anyone have a Snapdragon 845 single board computer for a low cost? $450 for the Thundercomm one... ouch...
The new Pi4 might beat/equal the nVidia nano now in CPU performance, wild.
AllanGHI'm wondering about the performance, too.....
My dad needed a computer on his desk at the local Senior's Center, where he is their VP, but the lady who is President is a bit of a snit (total control freak, actually) about things on the desks in the office.
She outlined an area on his desk that was no larger than an LCD monitor, and said that's all he was allocated to use, because anything larger would be "ugly". SMH
I screwed a nicely cased Pi-B3+ onto the back of an LCD monitor, hooked it up and gave him a wireless keyboard and mouse combo that he can lock in his desk drawer, and he's been deliriously happy about it ever since. I'm sure the fact that the President is green around the gills over it, doesn't hurt, either.
I've used it a few times (maintenance tasks, for the most part) and do see a bit of a lack in performance with a few things, but I'm used to much more horse power out of a desktop system.
I'm now looking forward to swapping-out the old board for the new one, and seeing what sort of difference it makes in terms of performance.
R_1how about putting the price of the unit reviewed rather than the price of the cheapest variant?
you tested and reviewed the 55 dollar 4GB unit, but list the price as 35 which is the 1GB unit.
the link to CanaKit goes to the 1GB unit NOT the unit reviewed.
if you review model A link to model A and reference model A

evilpaulIf you're interested in the Atomic Pi, see if you can get somebody to pay for part of the cost of a Compute Stick, cheap NUC, Latte Panda, etc for you, and buy one of those instead. It'll be just like an Atomic Pi, except functional without soldering crap to it, and there will be faster similar products produced to replace it in the future. And you can buy 30,001 of them if you want, because there's companies manufacturing them rather than pulling them out of talking Roombas that never made it to market.
[USER=96206]@op[/USER], did you try tinkering with chrome://flags and seeing if you could force hardware video decoding in Chromium? The Youtube channel Explaining Computers's guy seemed to get streaming video to work OK in his review. Also, I'm pretty sure that ~40 FPS in Quake III Arena was what my Voodoo Banshee managed to pull off. Or that might have been the used Voodoo 3 that replaced it. Details are fuzzy, for some reason.
g-unit1111I think this might be the time I actually take the plunge and buy a Raspberry Pi. Does anyone know what kind of OS it can support? Could I try loading my spare Windows 7 license on it? Will Pi 4 support memory cards larger than 32GB?
AllanGHOS support is, AFAIK:
NOOBS - no idea what that is, because I never tried it or read anything about it.
Debian Stretch, ported to the Pi...which works quite well, as long as you can ignore all the cutesy icons. o_O
Debian Jessie and Jessie-Lite, ported to the Pi. Same caveat about icons for the full-Jessie release.
For the Model 4, you'll need to download Debian Buster (still in testing), ported to the Pi....and Buster is backward compatible with all the Pi boards.
I also just ran across this review of the Buster iteration of the OS:
There are also several other CLI-only (no-GUI) releases that I've tinkered with, but Jessie-Lite was quite a bit better than what I saw.
I'm sure that there are other OS options available for the ARM Cortex-A53, and people have spoken of windows on the Pi (win10 ARM64 or win10 IoT Core), but I've never been interested enough to bother looking.
AllanGHOh....the platform will support up to 128GB MicroSD or SD cards (depending on the specific board you have).
You can get some answers to potential questions here.
And I just ran across some third-party OS offerings:
shivanspsLooks fine, the main bottleneck on the PI3 was the i/o, with USB3 that is gone.
The PI4 should the able to run Win10 ARM OK if a IGP driver is ever released.
Freespace 2 Demo would have been a much better game to test here... IF OpenGL is working in the distro.
bit_userQuote:The new Pi4 might beat/equal the nVidia nano now in CPU performance, wild.
Yeah, but the point of the Nvidia platforms wasn't really CPU performance.
Plus, their Nano is just a re-purposed Tegra X1, from 4 years ago. I guess they also disabled half of the CUDA cores (probably for power & yield reasons). Anyway, surpassing its CPU performance isn't really saying much...
bit_userQuote:I screwed a nicely cased Pi-B3+ onto the back of an LCD monitor,
Why not a NUC? ...unless it'd cost too much. AFAIK, they include a VESA mounting bracket.
bit_userQuote:If you're interested in the Atomic Pi, see if you can get somebody to pay for part of the cost of a Compute Stick, cheap NUC, Latte Panda, etc for you, and buy one of those instead.
Or an ODROID-H2, which looks to be an excellent implementation of the latest and greatest of Intel's low-power SoCs:
(BTW, they have US distributors - I think you needn't order it direct form SK)
bit_userQuote:I think this might be the time I actually take the plunge and buy a Raspberry Pi.
Do it.Quote:Does anyone know what kind of OS it can support? Could I try loading my spare Windows 7 license on it?
About running Windows on it, here's what their FAQ says:Quote:As of summer 2015, a version of Windows 10 is available for use on the Raspberry Pi 2 and 3. This is an entirely new version of the operating system designed exclusively for embedded use, dubbed the Windows 10 Internet of Things (IoT) Core. It does not include the user interface (shell) or the desktop operating system.

Christmas at the Cornhill - what's in store?
PUBLISHED: 18:59 02 December 2019
The multimillion pound Cornhill revamp transformed the spot into the perfect space to entertain the people of Ipswich – so what events are coming this Christmas?
Earlier this year Ipswich Borough Council hosted a number of free seasonal events - including a super hero day and a winter fun day, which both drew huge crowds to the town centre.
Read more: Grab your cape and fly high at Ipswich Cornhill
This year, they are keeping details of the January activities under wraps, with an announcement planned next month to share what people can expect of the 'special events'.
However, in the run-up to Christmas Day there are a number of other Christmas events to keep you entertained in Ipswich town centre.
The Christmas craft market
In 2018 the controversial craft market was placed in the middle of the Cornhill - but this year it has moved just a few steps away to Lloyds Avenue.
The big white tent returns to the town for the second year, with a wide range of stalls all displayed in a heated marquee until Monday, December 23.
Last year's event on the Cornhill, which took place shortly after the development work was completed, featured a range of goods from cheese to African carvings.

Ghost Caribou
After their popularity in 2018, the street performers are back in Ipswich town centre for late night shopping Thursdays.
Inspired by medieval English folklore, the two 'Caribou' puppets roam the Cornhill and the High Street as their 'trainer' guides their exploration through the town centre - before returning to the Cornhill for a magical storytelling projection show.
The approximate times are 4.30pm to 7.30pm - with two performances of the show and an intermission during that time.

The Farmers Market
The Farmers' Market in the centre of Ipswich returns the first Sunday of every month - with the next visit planned from 10am to 2pm on January, 5.
The top quality food offering sees the very best local producers come together to showcase their amazing products to a new audience.
These include locally reared, traditionally butchered pork from Greenacres, fresh fish and seafood, beautiful garden plants, freshly baked cakes and savouries from Alex's Artisan Bakery, jams and preserves from The Jam Shed, a range of chilli sauces and condiments, handcrafted gins and beers, Suffolk honey and fresh fruit and vegetables from Poppies Care Farm and Peach and Pippin.
In the weeks after Christmas there are also set to be a number of special events at the Cornhill, following the success of the winter schedule last year. Details will be announced by Ipswich Borough Council later this month so stay tuned.

Pawpaw rocks
My Pawpaw was a big rock collector. Mom still has jars full of his rocks and I went through one the other day. Much to my delight I found these beautiful Lace Agate (I think) rocks. I wish I could cut them myself, but since I can't I think I will see if I can get them cut. I'm thinking flat backs but leaving the tops natural would be cool.
I wish I knew where these rocks were collected. Granny and Pawpaw traveled all around the Western United States after they retired. These were probably picked up in the 60's or 70's in their travels. Pawpaw had the concrete steps from his mothers' house in his back yard as a display for his rock collection. I'll have to find a picture of that. I wish I could have transported the whole collection and the steps to my house!
Unrelated: I was interviewed by Love to Know, check it out.
I'm getting ready for Fiesta Art Fair in San Antonio which is in two weeks. If you would like more info sign up for my email list on the right side of the blog and I will send out an email soon.

Learning Never Ends
This past weekend I participated in intense work with fellow colleagues from Colorado and across the nation. #TeacherChampions is part of the amazing organization known as Collaborative for Student Success and Educators for Higher Standards.
What I love about this opportunity is the value and collaboration that occurs. Now, I have been to Washington, D.C. multiple times, and each time I come back more excited and refueled to be an educator and impact the profession.
Working with so many amazing educators is a blessing and gift. I'm grateful to be surrounded by these stellar leaders and learn so much from them. From the discussions to free time, I have the opportunity to hear so many perspectives of what is happening in other schools across the nation. I'm able to gain further insight on how I can impact and change the profession for my students and colleagues.
Being an educator requires me to be updated and innovative. Our world is changing rapidly and so are our students. I enjoy attending conferences and workshops to sharpen my instruction and work towards engaging my students to be great leaders for the future. What would the world be like with out teachers. Well, check out this video here.
It was a great weekend of learning. It was a great weekend of discovering how I can impact the educational profession. It was a great weekend to be surrounded with so many educators on the same mission...Elevate the Voices of All Educators.
Thank you to Katrina and all the #TeacherChampions who I engaged working with this weekend. Thank you for the friendship, the advice, and the leadership. Until next time, may all educators unite and do what is best for ALL our students.
Year 3...What's to come...
3-years ago I became part of an amazing group of educators from across the nation. I built a large Personal Learning Network (PLN) and expanded my knowledge in the field of education.
In addition, I have been able to find my voice as an educator and have been able to share this great learning experience with my students.
Our world has evolved greatly in last century. The 21st century has brought new insight to the educational field and policies that surround the profession. So many new high stakes are taking place and sometimes feels that we are just adding and dropping curriculum, testing, etc., continuously. However, the main question is "when will we find the right pathway?"
As a member and LEAD fellow of the America Achieves organization, I am growing as an educator in the profession. I have gained great knowledge about school policies and how to communicate effectively with legislators. I would have never imagined in my life that I would be doing such work as an educator.
Because of America Achieves I have been able to inform many people about the issues affecting education and training others on how to support education and establish an education system that supports what's best for ALL students and educators. I have been able to build my skills of advocating more and shaping policies along side with legislators using the many tools and skills America Achieves has given me.
I value education, and I value the education profession. Students matter! The value of education and how we as educators and legislators shape this "gift" to students is truly important for the future. There is more to education than the books or curriculum we use; funding and equity and assessment are several of many topics that affect education.
We have evolved from the traditional one room, one school house. We are in an era of continuous growth. We are in an era where students and educators have to prepare for the future. We are in an era where our world is shaped by the foundations of our schools.
I look forward to what year 3 of being a Colorado fellow and LEAD fellow for America Achieves will bring. I look forward to the new fellow's work, and how they shape the profession. Let year 3 begin!

Story from the Remington 870 Forum: Black Bear Encounter while Turkey Hunting with Remington 870.
So I was turkey hunting in the foothills of NC first weekend in May. My friend and I were on his hunting lease. I was in a ground blind 10 yards back in the pines off of a pasture on top of a knob. My friend was a quarter mile away in another spot. I had a hen decoy in the field near the corner of a small clover/oats food plot. Back in February, we had put some cracked corn out around the edge of the food plot. Just after 7 AM this young black bear shows up. He's about 15 yards away from me, nosing around in the food plot, probably looking for more corn he'd been feeding on the past 2 months. BTW, the corn was gone. In the second picture, he sees my decoy and I guess it startled him? He turns to his right and jumps the barb wire and walks straight at me. He walks just to the left side of the blind. Now, I had the side flaps on the blind closed up and I can't see him. My shotgun is standing up over in the corner because I was taking pictures with my stupid iphone. I'm sitting in a small camp chair. I gripped my pistol, didn't pull it out of the holster and slowly turned to my left to look out the unzipped tent entrance on the back left corner. The bear was 5 yards away, on all 4's looking right back at me! We looked at each other for a moment and then he lightly shakes his head and turns and runs off down into a ravine behind me.

New York City's dining scene is infinite, all-consuming and a proud tribute to the kaleidoscope of citizens who call the city home.
The top picks in this extract from our upcoming ebook 'Iconic Dishes New York,' come from across green markets, ethnic neighbourhood cuisine, food trucks and carts, tony Michelin-star restaurants and the city's never-ending dining scene.
So go ahead, take a bite out of the Big Apple – we promise you won't be sorry.
Hot dogs
The NYC frank is a classic. History traces the first frankfurter to a German who introduced it at Coney Island. The sausage is made of ground beef or pork, flavoured with mustard sauce, sauerkraut, garlic, smoked and cooked and slid between slabs of hot dog buns to make for a chunky bite. This humble eat is available at push carts and fancy eateries around the city too.
Yet another import from German soldiers from Hamburg who docked in the 1820s in New York. While the first burgers (or hamburgs, as they were initially called) were made from meat of pork or beef, in time the disc of meat was slipped between a bun with layers of salad greens encasing it. From New York the hamburger became ubiquitous at diners across America and acquired a global following.
Then came the Italians bringing along their Neopolitan flavours to NYC. The first pizzeria was set up by Gennaro Lombardi in the 1800s. The iconic pizzeria stands even today, drawing locals and tourists alike while pizza joints are dotted across the city for New Yorkers to bite into a slice. The pizza here has a thin crust, and can be folded, napkin-like, for a bite and is flavoured with oregano and cheese.
Lots more in our upcoming ebook 'Iconic Dishes New York'. Stay tuned!

2017 UK Obligation Tables
The initial release of the UK 2017 packaging obligation tables has today, 15 May 2017, been published by the regulator.
This data indicates the levels of packaging waste recycling the UK need to achieve in the 2017 compliance year in order to meet government set recycling targets. It is important to note that this data doesn't include any potential late or new registrants to the system which will impact the data as we move through 2017.
These initial figures allow us to make comparisons between the final count of 2016 registered producers and the number of registered producers by the 15 April 2017. The final 2016 register was made up of 7,008 Full Producers and 450 Small Producers, whilst the figures just released for 2017 confirm that there are currently 6,675 Full Producers and 412 Small Producers registered.
We can therefore conclude that a number of obligated producers have yet to register for 2017.
The below table outlines the UK PRN requirement for the amount of tonnages which need to be recycled for 2017 compared to the end of year 2016.
The PRN requirement is the total amount of recovery and recycling that is required by the UK in a given compliance (calendar) year. This is calculated using the UK Obligation Tables, which show the total amount of packaging handled by UK producers and under what activity. The obligated tonnages are then multiplied by the recycling targets for that particular year, and any additional tonnages relating to producers using the small producer method are added. As the 2017 PRN requirement has only just been released, these figures will most likely increase slightly throughout the year as any outstanding producers register with a compliance scheme or agency. It is worth being aware that this is the total requirement and there has been no tonnages removed due to 2017 Carry in PRNs.
Q1 Verified Packaging Recycling Data
The Environment Agency has also just released the Verified Q1 2017 Recycling Data, which doesn't look to show too much change from the last set of unverified data. It appears that Plastic remains the single material to pay careful consideration to given the reduction in the recycling levels originally reported in the initial set of unverified Q1 data as we reported here.
The graphs below indicate the recycling data with the carry-in from 2016 and without such carry-in, using the verified Q1 recycling data and 2017 obligation data to date.
Overall, at this 25% marker for the year, we can see a fairly positive picture in terms of recycling levels at the end of Q1. As mentioned, and as a cautionary note, there is still some uncertainty and potential PRN volatility regarding Plastic, with the recycling levels anticipated for Plastic in Q2 expected to be down on Q1 levels. This expectation that Plastic recycling levels may drop is due to a combination of higher container shipping costs (particularly in late March, April and early May) and also the impact of more stringent quality control in China under the banner 'Operation Sword'. We will also be keeping a close eye on Glass recycling levels as they are close to the minimum required levels for us to be on track for the year. The other materials look quite comfortable already for this stage of the year however experience tells us that in this market much can change and quite quickly too.
If you have any questions regarding the data, please contact our packaging team at email@example.com

Source: Village Voice, coverage of the first CD release of Coleman's Crisis Music.
In a scene from Ornette: Made in America, Shirley Clarke's unconventional — and unforgettable — documentary portrait of Ornette Coleman, the musician and composer is on a New York City sidewalk in 1968. Deadly earnest, he asks his drummer the following: "What is it that you do that's different from other drummers?…It's obvious you don't have anything to go by, yet you're playing as if you did, and that is a very modern way of playing. I'm trying to find out what method you use to be correct, to be right. You're more right than wrong." The drummer, smacking away at chewing gum, responds, "Aw, I dunno. I don't have any particular method or anything."

Presented by:
Queen City's native son Adrian Crutchfield celebrates the smooth sounds of the legendary groove master, saxophonist Grover Washington Jr. Crutchfield and his band will perform music from across Washington's career, from his Grammy Award winning album Winelight to his popular 70's classic Mister Magic.
More Variety. More Fun. More Jazz.
The Jazz Arts rolls out its new fall 2018 program expansion, Premiere Thursdays!
Premiere Thursdays presents a fresh and carefully curated kaleidoscope of exclusively themed programming for one-night only, or as a "premiere" to the popular JAZZ ROOM weekend shows.
Saxophonist and Charlotte native Adrian Crutchfield is known for his diverse musical abilities, pulling from a variety of genres in order to create a neo-soul sound all his own. After receiving his first saxophone at age 4 from Kenny G during a concert in Virginia, Adrian has gone on to become "one of his generation's most prolific and successful professional musicians." Having worked with a range of artists including Branford Marsalis, Lionel Richie, Ceelo Green and Bette Midler, Adrian toured and recorded with Prince and the New Power Generation as the leader of the band's 11-piece horn section from 2012-2016.
Known as one of the most influential saxophonists of his time, Grover Washington Jr. was a trail blazer in his field. First influenced by his father who also played the sax, Washington was performing in the New York club scene by age 12. Within his career, Grover was recorded on hits such as "Inner City Blues" and "Just the Two of Us" and with labels ranging from Motown Records to Columbia Records. Washington is known for his unique sound, giving his saxophone playing a full range of personal voices.

There are some words that just creep under the skin, like toxic molasses (that's one of them). What's so wonderful about the English language is also its biggest downfall: associations. Certain phrases and utterances carry the weight that make them as desirable as pungent yolk… (gross).
With The Great British Bake Off up and running, choruses of people are echoing their hatred of the word 'moist'. And rightly so. It's the sociopath's favourite word based solely on the fact that everyone hates it…
Oxford Dictionary recently started a campaign #OneWorldMap that provided the opportunity to find the least favourite English word across the globe. There was no criteria so it was pretty much a subjective experiment to see if there are some words that are universally hated.
The results are below with surprising words and not so surprising words according to the country:
What really isn't surprising is the consensus that 'moist' is the worst English word across all English-speaking countries. It truly is horrible. The collective population of UK, USA, Canada and Australia is 449 million people. Roughly this many people hate 'moist' so please stop saying it.
Answers submitted will allow Oxford Dictionaries to map out the world according to least popular words and what generations, genders and countries hate accordingly.
Latest Stories
The project has 10,000 submissions right now with a 52/48 split between men and women. It'd be interesting to see if men hate the word 'moist' as much as women…
What is also quite interesting is what non-English speaking countries put as their least favourite word. India's was, hilariously, 'love'.
The word 'no' is pretty despised across the board proving, once and for all, human beings really don't like being told they can't have or do things…
