2026 verdict
Geekom GT1 Mega Ultra 9 is the clear winner in this mini PC matchup, backed by a longer warranty, faster DDR5 memory, and far more headroom: 32GB of RAM and a 2TB SSD against the 8GB and 256GB on the GMKtec NucBox G3S (8GB + 256GB).
The Core Ultra 9 185H, Arc graphics, dual USB4 ports, Wi-Fi 7 and dual 2.5G Ethernet put it in a different performance class, built for creative software, multi-monitor office setups and light virtualization rather than basic browsing. The GMKtec NucBox G3S (8GB + 256GB) is not trying to compete on that ground: it is a much cheaper entry-level box built around a four-core Intel N95, and it still covers browsing, streaming, office work and a VESA-mounted living room setup without complaint. Both machines ship with an HDMI cable and a VESA mount in the box, so the day-to-day setup is equally simple either way. Choose the Geekom GT1 Mega Ultra 9 for demanding, multitasking-heavy work, and choose the GMKtec NucBox G3S (8GB + 256GB) when a basic Windows desktop behind a monitor is all the job calls for.
