2026 verdict
Local AI work is why the Geekom A9 Mega (64GB + 1TB) wins this mini PC comparison against the GMKtec NucBox G3 Pro (16GB + 512GB).
It ships 64GB of LPDDR5X at 7500 MT/s, Radeon 8060S graphics, dual 2.5G Ethernet, Wi-Fi 7 and a three-year warranty, while the G3 Pro is a 16GB DDR4 i3 box in plastic with HDMI 1.4 outputs and a one-year warranty. The GMKtec NucBox G3 Pro (16GB + 512GB) is still the far more affordable, better-reviewed machine and keeps two SO-DIMM slots plus a spare M.2 bay for later upgrades. Pick the Geekom A9 Mega (64GB + 1TB) for GPU-class graphics and a 64GB memory pool; pick the G3 Pro for a cheap, expandable office or home-lab box.
