### 树莓派 4 的新特性






树莓派 4 开始支持双 4k 显示器设置 —— 如果你对此有所需求的话。除此外，它还配备了更强大的处理器，其搭载的 RAM 最高可达 4 GB，这几乎可以媲美一个中端的便携电脑。


本次配置升级使树莓派可以参与[迷你 Linux 机](https://itsfoss.com/linux-based-mini-pc/)市场的竞争，而依旧 35 美元的起始售价使其比[其它单板计算机](https://itsfoss.com/raspberry-pi-alternatives/)更具优势。


树莓派 4 发布不久，各大主要的在线商店就几乎销售一空。那么，我们来看看它有哪些新卖点吧。

请注意，[运行树莓派需要额外的配件](https://itsfoss.com/things-you-need-to-get-your-raspberry-pi-working/)，这就是为什么官方提供了可选的基础套件，套件中包含了所有必需的支持配件。


#### 树莓派 4 桌面套件

### 树莓派 4 的前景


拥有所有这些配置后，树莓派 4 无疑会成为同类产品中最好的之一。同样，相比购买入门级桌面计算机，购买树莓派 4 也会是更好的选择。你可以只花很便宜的价格，就能轻松访问文档、管理电子表格，以及完成更多其它操作。


我绝对会考虑购买树莓派 4 作为备用（但强大）的入门级桌面计算机，但不会配备 4k 显示器，但依据文档，树莓派 4 肯定是支持双 4k 显示设置的。


你怎么评价最新版的树莓派 4B? 欢迎在评论中说出你的想法。

OK
*Brief: Raspberry Pi 4 is here with the upgraded technical specifications. You get up to 4 GB of RAM and you can connect two 4K displays with it. With the new hardware, you should be more comfortable using it as a desktop. Starting price remains the $35 like the previous models. *

The Raspberry Pi Foundation has just launched the new [Raspberry Pi 4 Model B](https://www.raspberrypi.org/products/raspberry-pi-4-model-b/).

It comes with some impressive upgrades which makes one of the most powerful [single board computers](https://itsfoss.com/raspberry-pi-alternatives/) under $40.

## What’s new in Raspberry Pi 4?

The Raspberry Pi 4 now supports a dual 4K monitor setup – if that is what you are looking for. In addition to this, you get a more powerful processor which can be coupled with up to 4 GB of RAM. That’s almost equivalent to a mid-end laptop.

The upgraded specification makes it a competitor in the [Linux mini-PC](https://itsfoss.com/linux-based-mini-pc/) segment while the same price tag of $35 gives it an edge over [other single board computers](https://itsfoss.com/raspberry-pi-alternatives/).

Right after the launch, it’s almost out of stock at major online stores. So, let us take a look at what makes it so impressive.

### Raspberry Pi 4 key specifications

![Raspberry Pi 4 Tech Specs](https://itsfoss.com/content/images/wordpress/2019/06/raspberry-pi-4-tech-specs.jpg)

- Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- Up to 4GB RAM (choices are 1 GB, 2 GB and 4 GB)
- WiFi and Bluetooth 5.0
- 2 USB 3.0 and a USB 2.0 ports
- 40 pin GPIO header (backward compatible)
- 2 micro-HDMI ports (supports 4K displays)
- USB-C (power supply)
- Gigabit Ethernet

If you are curious to know more, do check out the [official tech specs](https://www.raspberrypi.org/products/raspberry-pi-4-model-b/specifications/) on their website.

## Pricing and availability

The pricing for just the Raspberry Pi 4 board starts from $35 and depending on the choice of RAM (1-4 GB), the cost shall vary.

- Raspberry Pi 4 with 1 GB RAM: $35
- Raspberry Pi 4 with 2 GB RAM: $45
- Raspberry Pi 4 with 4 GB RAM: $55

Raspberry Pi 4 is available from different vendors depending on your country. It’s getting out of stock so you should either hurry up or wait for a few days/weeks. You can get purchase information on its official webpage.

You should note that [you need to have additional accessories in order to run Raspberry Pi](https://itsfoss.com/things-you-need-to-get-your-raspberry-pi-working/). This is why there are several starter kits available to give you all the necessary supporting accessories.

### Raspberry Pi 4 desktop Kit

![Raspberry Pi 4 Desktop Kit](https://itsfoss.com/content/images/wordpress/2019/06/raspberry-pi-4-desktop-kit-800x427.jpg)

You can also purchase the official Raspberry Pi 4 desktop kit that comes with a Raspberry Pi 4, its case, keyboard, mouse, micro HDMI cables, USB-C power supply, user guide and 16GB [microSD card with Raspbian installed](https://itsfoss.com/tutorial-how-to-install-raspberry-pi-os-raspbian-wheezy/).

The entire kit is in red and white color and it looks pretty (if you care for the looks). You can get the purchase information on Raspberry Pi website.

### Raspberry Pi 4 is promising

With all that spec buff, it is definitely going to be one of the best out there. Also, instead of getting an entry-level desktop, Raspberry Pi 4 will be a better choice. You can easily access your documents, manage your spreadsheets, and do a lot of things at a cheaper price tag.

I’m definitely considering to purchase the Raspberry Pi 4 as a spare (but a powerful) entry-level desktop. Well, I won’t be going for the 4K dual monitor setup, but it surely is capable of that, at least on paper.
