单板计算机（SBC）领域因树莓派新产品的推出再次活跃起来。


这款被称为 **树莓派 5** 的新产品，是其非常受欢迎的前身树莓派 4（于 2019 年推出）的进化版。


下面，我们来探讨它的新鲜亮点，以及何时何地可以将其买到手。


### ? 树莓派 5 的新变化是什么？






**树莓派 5 是一款足以称得上强大的后继产品**，其全新设计的平台搭载了在英国开发的**自行设计的芯片**。


与树莓派 4 比较，**树莓派 5 的性能提升了一倍以上** ，这主要得益于硬件和软件的改进。他们还补充说：



> 
> 与树莓派 4 相较，我们的 CPU 和 GPU 性能提高了两到三倍，在内存和 I/O 带宽方面也有大约两倍的增长；而且这是我们首次在旗舰树莓派设备上使用了自家的树莓派芯片。
>

尽管外形并无明显改变，树莓派 5 **仍然保留了信用卡大小的尺寸**。变化主要体现在端口的位置上。


为了配合这款 SBC 的发布，树莓派团队积极开发了适合的新版本树莓派操作系统。它**基于 [Debian 12 “Bookworm”](https://news.itsfoss.com/debian-12-release/) 版本**，所以你可以期待有很多改进。


这个更新的操作系统预计将在 **2023 年 10 月中旬** 发布，将过渡到 [Wayfire](https://wayfire.org/) Wayland 合成器系统，**摒弃了 X11**。


### ? 树莓派 5 的关键参数

The Single-board computers (SBC) space is livening up again thanks to the launch of a new offering by Raspberry Pi.

Called the '**Raspberry Pi 5'**, it is an evolution over its very popular predecessor, the Raspberry Pi 4, which was launched back in 2019.

So, let's see what it has to offer and when/where you can get it from.

## 🆕 What's New in Raspberry Pi 5?

The** Raspberry Pi 5 is a sufficiently powerful successor** that has a completely redesigned platform, featuring **in-house designed silicon** developed in the UK.

In comparison to the Raspberry Pi 4, the **Raspberry Pi 5 is over twice as powerful **thanks to the improvements in hardware and software.** **They also added that:

Compared to Raspberry Pi 4, we have between two and three times the CPU and GPU performance; roughly twice the memory and I/O bandwidth; and for the first time we have Raspberry Pi silicon on a flagship Raspberry Pi device.

Even the form factor doesn't see much of a change**,** with the Raspberry Pi 5 **retaining the** **credit-card sized footprint**, with changes mostly to the placement of ports.

To further complement the release of this SBC, the Raspberry Pi team has been busy readying up **a new release of Raspberry Pi OS**. It is **based on the ****Debian 12 'Bookworm'**** release**, so you can expect loads of improvements.

The updated OS is set to launch in **mid-October 2023**, with a transition to the [Wayfire](https://wayfire.org/?ref=news.itsfoss.com) Wayland compositor system, **doing away with X11**.

## 📝 Raspberry Pi 5: Key Specifications

![a photo of the raspberry pi 5 computer](https://news.itsfoss.com/content/images/2023/09/R_Pi5_1.jpg)

So, you are maybe wondering; what hardware the Raspberry Pi 5 is packing?

Well, for starters, the Raspberry Pi 5 is **powered by a new 16 nm application processor from Broadcom** called '**BCM2712**'.

It features **a** **quad-core 64-bit Arm Cortex-A76 processor** running at a nominal **2.4 GHz**, with **512 KB per-core L2 caches** and a **2 MB shared L3 cache**.

All of that is complemented by a new GPU in the form of Broadcom's **VideoCore VII**, with **completely open-source Mesa drivers**.

Then there's the new **'RP1' I/O controller** that **handles various I/O ports** such as the **USB 2.0/3.0**, **Gigabit Ethernet**, **MIPI transceivers**, and the** usual GPIO ports**.

And finally, we have the new** 'DA9091' power-management IC** by [Renesas](https://www.renesas.com/us/en?ref=news.itsfoss.com) that **handles power distribution** around the board with **eight separate switch-mode power supplies** to generate different voltages according to the Raspberry Pi 5's needs.

Other than that, here are some of the other notable highlights:

- Dedicated Power Button
- Dual-Band 802.11ac Wi-Fi
- 4 GB/8 GB Memory Variants
- 2x 4Kp60 HDMI Display Output
- 2x 4-lane MIPI camera/display transceivers
- Bluetooth 5.0 / Bluetooth Low Energy (BLE)

Raspberry Pi 5 sounds like something that should enable you to build cool projects, potentially better than existing [Raspberry Pi projects](https://itsfoss.com/raspberry-pi-projects/?ref=news.itsfoss.com).

## Raspberry Pi 5 Accessories 🦾

![a photo of the official raspberry pi case accessory](https://news.itsfoss.com/content/images/2023/09/R_Pi5_2.jpg)

As is tradition, the Raspberry 5 has launched with various official accessories.

Take for example **the case, which has an integrated fan**, tuned for low noise, and extended usages.

Then there's another cooling accessory in the form of an '**active cooler**', that features an aluminum heat sink with a fan that can be directly mounted on to the board.

Owing to the **increased peak power requirements**, they are also offering **a 27 W USB-C power supply** for tinkerers to push their Raspberry Pi 5 to the limits.

There are a few more [Raspberry Pi accessories](https://itsfoss.com/raspberry-pi-accessories/?ref=news.itsfoss.com) available that I didn't mention here, like display cables, m.2 hat, and more. I'm sure there could be more in the near future.

I highly suggest you go through the official [announcement blog](https://www.raspberrypi.com/news/introducing-raspberry-pi-5/?ref=news.itsfoss.com) to get into the finer details of this interesting SBC.

### 💰 Pricing and Availability

The Raspberry Pi 5 is being offered in **two variants**, and prices start at **$60 for the 4 GB**, and **$80 for the 8 GB variant**.

It is **up for pre-order** through various [approved resellers](https://www.raspberrypi.com/resellers/?ref=news.itsfoss.com), with shipping to commence by the end of October.

They have **limited sales to just individual buyers** until the end of this year (2023), to avoid any supply chain issues.
