Raspberry Pi CM5 is 2-3x faster, drop-in upgrade (mostly)
The Raspberry Pi Compute Module 5 is smaller than a credit card, and I already have it gaming in 4K with an eGPU, running a Kubernetes cluster, and I even upgraded my NEC Commercial display from a CM4 to CM5, just swapping the Compute Modules!
The Compute Module 4 was hard to get for years. It launched right after the COVID supply chain crisis, leading to insane scalper pricing.
It was so useful, though, that Raspberry Pi sold every unit they made, and they're inside everything: from commercial 3D printers, to TVs, to IP KVM cards.
