Raspberry Pi5

The Raspberry Pi foundation announced the Raspberry Pi 5 on the 28th of September. The official announcement can be found HERE

 

It is approximately 2.5 times faster than the Pi4 for CPU workloads and GPU workloads vary between 2 and 4.5 times faster.

 

The Pi5 has an official heatsink/fan and a fan header. Some heat tests I saw showed that without the heatsink it would overheat and throttle itself within 30 seconds.

There was also a new case designed to fit the Pi5 and its heatsink.

 

Unfortunately I will have to wait for the other case manufacturers (like Flirc) to come up with new designs. I have also been in contact with BitScope who make the Edge Cluster 12 that I have two of, as it looks like they need to make some changes to cool the Pi5.

Key features:

  • 2.4GHz quad-core 64-bit Arm Cortex-A76 CPU
  • VideoCore VII GPU, supporting OpenGL ES 3.1, Vulkan 1.2
  • Dual 4Kp60 HDMI® display output
  • 4Kp60 HEVC decoder
  • Dual-band 802.11ac Wi-Fi®
  • Bluetooth 5.0 / Bluetooth Low Energy (BLE)
  • High-speed microSD card interface with SDR104 mode support
  • 2 x USB 3.0 ports, supporting simultaneous 5Gbps operation
  • 2 x USB 2.0 ports
  • Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT, coming soon)
  • 2 x 4-lane MIPI camera/display transceivers
  • PCIe 2.0 x1 interface for fast peripherals
  • Raspberry Pi standard 40-pin GPIO header
  • Real-time clock
  • Power button

Its finally got a real-time clock, a power button and PCIe. The battery and holder for the clock are optional extras.

It comes in 4GB and 8GB versions. There is a rumor they may offer a 16GB model later. Official pricing has increased and is $60 (USD) for the 4GB and $80 (USD) for the 8GB.

I would have liked 2.5G networking and more CPU cores are always welcome. Certainly an evolution from the Pi4 but only really catching up to the competition.

I saw a conspiracy theory on the Raspberry Pi forums that Ebon (Upton) was waiting for Christmas to release Raspberry Pi OS based on Debian 12 (aka Bookworm) at the same time as the Pi5. It seems that might not have been far off, apart from the timing.

 

Updates and Corrections

Flirc have updated their website showing a Pi5 case.

The Pi case has its own fan and doesn't have room for the official heatsink/fan. You would only need the official case or the heatsink/fan, not both.

The close-up photos of the Pi5 show resistor points for  memory sizes 1, 2, 4 and 8GB. There is nothing for 16GB without a board revision. It does however indicate they can produce 1 and 2GB variants.
