2026 verdict

The A6 runs an eight-core Ryzen 7 6800H with Radeon 680M graphics and DDR5 memory, a noticeably more capable platform than the G3 Pro's four-core Intel Core i3-10110U on older DDR4, and it ships with double the storage at 1TB against the G3 Pro's 512GB. The G3 Pro's main draw is a lower price, the whole reason to consider it here, along with a second free M.2 SATA bay for anyone who wants to add a drive later rather than pay for more capacity upfront. Both include a VESA mount, an HDMI cable and Windows 11 Pro in a similarly tiny footprint, but the A6 adds USB4 and an SD card reader that the G3 Pro does not have. Buyers who want a genuinely capable everyday desktop with room to grow should choose the Geekom A6 (Ryzen 7 16GB + 1TB), while shoppers on a tight budget who just need a basic Windows box should pick the GMKtec NucBox G3 Pro (16GB + 512GB).
