Raspberry Pi 4 Released

Raspberry Pi 4 Released

The Raspberry Pi Foundation has announced the release of the Raspberry Pi 4, a tiny computer that is easily capable of running Linux and other operating systems. It is a significant upgrade over the existing model 3, featuring a boost in CPU and GPU speed, USB-C power, but most importantly it is now available with differing amounts of onboard RAM (1GB, 2GB and 4GB).

Pricing starts at £34 for the baseline 1GB model, with the 2GB (£44) and 4GB (£54) models costing a little more. Toms hardware have already taken a look at the new RPi and have performed some interesting benchmarks:

As you can see, the new model outperforms previous generations by a large margin. The design improvements to the new gigabit ethernet and SD card write speeds will also provide a huge advantage to those using the RPi as a server, as these were previously limiting factors.


Another important design improvement is the use of a USB-C power port. Previous generations used a Micro-USB header, however there were often undervoltage warnings when using any power adaptor other than those designed specifically for the RPi (which provided a slightly higher than spec 5.1V @ 2.5A). Switching to USB-C should mitigate this problem for the most part.

Here are the full specifications:

  • Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
  • 1GB, 2GB or 4GB LPDDR4-2400 SDRAM (depending on model)
  • 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
  • Gigabit Ethernet
  • 2 USB 3.0 ports; 2 USB 2.0 ports.
  • Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
  • 2 × micro-HDMI ports (up to 4kp60 supported)
  • 2-lane MIPI DSI display port
  • 2-lane MIPI CSI camera port
  • 4-pole stereo audio and composite video port
  • H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
  • OpenGL ES 3.0 graphics
  • Micro-SD card slot for loading operating system and data storage
  • 5V DC via USB-C connector (minimum 3A*)
  • 5V DC via GPIO header (minimum 3A*)
  • Power over Ethernet (PoE) enabled (requires separate PoE HAT)
  • Operating temperature: 0 – 50 degrees C ambient
