Data from Amazon and official Geekom and GMKtec sites.
2026 verdict
The GMKtec NucBox M5 Ultra (32GB + 512GB) is the better-equipped budget desktop of these two, winning on price and memory capacity with 32GB of dual-channel DDR4 that reaches 64GB.
The Geekom A5 Pro (Ryzen 5 16GB + 512GB) fights back with the better owner rating and a three-year warranty, a metal chassis, more USB ports and an SD card reader, but it ships 16GB and uses an older Zen 3 chip. Both are quiet office machines rather than gaming rigs, and both keep upgradeable memory and Windows 11 Pro. Buy the GMKtec NucBox M5 Ultra (32GB + 512GB) for more memory for the money and home-lab potential from its dual 2.5G ports, and the Geekom A5 Pro (Ryzen 5 16GB + 512GB) for a tidier all-round office box with a longer warranty and an SD reader.

Networking

What owners say
Owners of both mini PCs describe an easy setup out of the box, and both are quiet and compact enough to disappear on a desk. Geekom A5 Pro (Ryzen 5 16GB + 512GB) owners highlight painless setup with Windows 11 Pro and no bloatware, a small aluminium body that fits anywhere and enough speed for office work and even 2D and 3D CAD; their main warning is the storage layout, with no 2.5-inch bay, only M.2 slots. GMKtec NucBox M5 Ultra (32GB + 512GB) owners lean into home-lab and Linux duty, running pfSense, Proxmox and Kubernetes on its dual 2.5G ports, and they praise the performance per watt and the support they received; a few note a sleep-wake bug and warm graphics under sustained gaming.

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
