Raspberry Pi 5: What's New and Which RAM Size to Choose

The Raspberry Pi 5 is the most powerful single-board computer in the Raspberry Pi lineup. It keeps the familiar credit-card format but adds a much faster processor, a new graphics core and a set of connectors that open the door to faster storage and more demanding projects.

What's new compared with the Pi 4

  • Faster processor: a 2.4 GHz quad-core Arm Cortex-A76 CPU, a big step up in speed over the Pi 4.
  • New graphics: VideoCore VII GPU with dual micro-HDMI outputs supporting 4K at 60 Hz.
  • PCIe connector: a single-lane PCI Express interface for NVMe SSDs and other fast peripherals through compatible accessories.
  • Two USB 3.0 ports and two USB 2.0 ports, plus Gigabit Ethernet.
  • Two 4-lane MIPI connectors that can be used for cameras or displays.
  • Real-time clock with a battery connector, and a power button.

Which RAM size should you choose?

  • 1 GB / 2 GB: light tasks such as a small server, network tools, IoT gateways and learning projects.
  • 4 GB: the best balance for most people: desktop use, Home Assistant, media centres, development and small containers.
  • 8 GB: heavier multitasking, several services at once, virtual machines and computer vision work.
  • 16 GB: demanding workloads, larger databases and memory-hungry software.

What to buy together with the board

  • Power supply: the Pi 5 needs a good USB-C power supply; the official 5 V / 5 A (27 W) one is recommended to avoid limits on USB devices.
  • Cooling: an active cooler keeps performance steady under load.
  • Storage: a fast microSD card, or an NVMe SSD with a compatible adapter for much better speed.
  • Case and cables: a case that leaves room for cooling, and a micro-HDMI cable for the display.

Project ideas

  • Home server, network storage and media centre.
  • Smart home hub.
  • Robotics and companion computer for drones and rovers.
  • Computer vision and edge AI experiments with a camera.
  • A compact desktop computer for work and learning.

Which model suits you?

If you are not sure, start with the 4 GB version for general use, and take 8 GB or 16 GB when you already know your workload will be heavy. See all boards in our Raspberry Pi collection, and read our comparison of all Raspberry Pi models.
