2026 verdict
More memory, more storage: GMKtec NucBox M6 Ultra (32GB + 1TB) wins this mini PC pairing outright, doubling the installed memory to 32GB of DDR5 against the Geekom A5 Pro (Ryzen 5 16GB + 512GB)'s 16GB of DDR4, and expanding storage to 1TB against 512GB. The M6 Ultra also runs a six-core Ryzen 5 7640HS with Radeon 760M graphics, dual 2.5G Ethernet, Wi-Fi 6E and a free second M.2 slot for future storage. The Geekom A5 Pro (Ryzen 5 16GB + 512GB) answers with a three-year warranty against the M6 Ultra's single year, plus an all-aluminium chassis, a Kensington lock, an SD card reader and a VESA mount with HDMI cable included, none of which is confirmed on the GMKtec. Buy the GMKtec NucBox M6 Ultra (32GB + 1TB) for more memory and storage from the start and dual networking; buy the Geekom A5 Pro (Ryzen 5 16GB + 512GB) for the longer warranty and a more complete accessory bundle.
