2026 verdict
For a compact desktop backed by real after-sales coverage, Geekom A8 (Ryzen 7 16GB + 1TB) has the edge over GMKtec NucBox M6 Ultra (32GB + 1TB) in this mini PC comparison, with a three-year warranty against the M6 Ultra's one year, faster 5600 MT/s DDR5 memory against 4800 MT/s, and the newer Radeon 780M graphics against the M6 Ultra's Radeon 760M. Both ship with a 1TB PCIe drive and DDR5 memory, so the GMKtec's main structural advantage is raw capacity: it arrives with 32GB installed against 16GB in the Geekom, plus a second free M.2 slot and dual 2.5G Ethernet for a home-lab or firewall setup. The Geekom A8 (Ryzen 7 16GB + 1TB) answers with an SD card reader, which the GMKtec lacks, along with a VESA mount included in the box. Pick the Geekom A8 (Ryzen 7 16GB + 1TB) for the longer warranty, quicker memory and newer graphics; pick the GMKtec NucBox M6 Ultra (32GB + 1TB) if double the installed memory and dual networking matter more than warranty length.
