✓ What We Love

  • 2-3x faster than Raspberry Pi 4
  • PCIe 2.0 connector enables NVMe SSD booting
  • Dual 4K HDMI output at 60fps
  • Real-time clock battery-backed
  • Mature OS and software ecosystem

! Worth Knowing

  • Requires 27W USB-C power supply for full performance
  • Runs hot — active cooling required
  • More expensive than previous Pi generations

Quick Verdict

The Raspberry Pi 5 is the leap the community has been waiting for. The BCM2712 chip delivers 2-3x the CPU performance of Pi 4, genuine PCIe for NVMe SSDs, and dual 4K HDMI. Fast enough for genuine desktop PC use for light work.

Performance

Cortex-A76 cores at 2.4GHz make a dramatic difference. Compiling code, running multiple browser tabs, and desktop tasks that crawled on Pi 4 are now snappy.

PCIe and NVMe

The PCIe 2.0 connector transforms Pi projects. With the official M.2 HAT you can attach an NVMe SSD and boot from it — dramatically faster and more reliable than SD card storage for always-on projects like home servers.

Cooling

The Pi 5 runs hot under load. The official Raspberry Pi Active Cooler (£5) is the best option. Do not run Pi 5 in a standard Pi 4 case.

Who Should Buy This?

Makers, hobbyists, home lab enthusiasts, and anyone who has been waiting for a Pi capable of handling demanding projects.

Frequently Asked Questions

Is Pi 5 compatible with Pi 4 accessories?
Many accessories work but power requirements (27W) and case dimensions changed. Check compatibility before buying Pi 4 cases or HATs.
Do I need active cooling?
Strongly recommended. Without cooling under sustained load, the Pi 5 throttles CPU frequency to manage heat.
What OS runs on Pi 5?
Raspberry Pi OS (Debian-based) is the official choice. Ubuntu 24.04, Fedora, and many others also support Pi 5.
