Which is better for a home server?

The Pi 5. The Cortex-A76 cores and PCIe NVMe boot make it far better for containers, databases and media serving. The 1 GB Pi 4 runs out of memory quickly under Docker.

Is the Pi 5 worth the extra over the Pi 4?

Yes if you compile code, run Docker or drive two 4K screens. For a single light task like a Pi-hole or a sensor logger, the Pi 4 does the job for less.

Both are durable boards with no moving parts. The Pi 5 has more headroom for future software, while the Pi 4 has a longer track record and cheaper replacement cost.

Can I use my Pi 4 case and cables with the Pi 5?

No. The Pi 5 needs new camera and display cables, and most Pi 4 cases do not fit. Budget for a Pi 5 case and the official 27 W USB-C power supply.

Do both support dual monitors?

Yes, both have two micro HDMI ports. The Pi 5 drives two 4Kp60 displays with HDR at once; the Pi 4 handles dual displays at lower refresh rates.

Which should I buy for retro gaming?

The Pi 5 gives higher frame rates and smoother emulation, but needs active cooling. The Pi 4 is cheaper and well supported by RetroPie builds.
