Geekom A7 Max (Ryzen 9) vs GMKtec NucBox G3S (8GB + 256GB)

Full Mini PCs comparison in 2026

Updated November 2026
Data from the official Geekom and GMKtec sites.
2026 verdict
Eight Zen 4 cores against four Alder Lake-N ones: the Geekom A7 Max (Ryzen 9) is the clear winner in this mini PC matchup, ahead of the GMKtec NucBox G3S (8GB + 256GB) on memory type, memory capacity, storage capacity and warranty length.
The A7 Max pairs its Ryzen 9 7940HS and Radeon 780M graphics with DDR5 memory, a 1TB PCIe 4.0 SSD, dual 2.5G Ethernet and two 40Gbps USB4 ports, all in an aluminium chassis with an SD card reader and a Kensington lock. The NucBox G3S answers with the one thing that actually moves buyers on a tight budget, a noticeably lower price, plus a second internal M.2 slot for cheap storage expansion that the A7 Max's single-slot design does not offer. Both include an HDMI cable and a VESA mount and run Windows 11 Pro out of the box. Anyone who wants real desktop-class performance, faster memory and more headroom to grow should buy the Geekom A7 Max (Ryzen 9); anyone who just needs a light Windows box behind a monitor at the lowest possible cost should buy the GMKtec NucBox G3S (8GB + 256GB).
