This is close to a sweep: the Geekom GT1 Mega Ultra 9 beats the GMKtec NucBox G3 Pro (16GB + 512GB) in owner rating, warranty length, memory type, memory speed, memory capacity and storage capacity, leaving the G3 Pro with only its lower price to fall back on. The GT1 Mega Ultra 9 pairs an Intel Core Ultra 9 185H with 32GB of DDR5 and a 2TB SSD in an aluminum chassis owners run for Adobe Creative Suite work, DaVinci Resolve editing and light virtualization, a different tier entirely from the G3 Pro's four-core Core i3-10110U, 16GB of DDR4 and 512GB drive built for browsing and documents. What the G3 Pro does offer is a second free M.2 SATA bay for gradual storage expansion, something the GT1 Mega Ultra 9's single M.2 2280 slot does not include. Both run Windows 11 Pro and include a VESA mount and HDMI cable, but the GT1 Mega Ultra 9 adds dual 2.5G Ethernet, Wi-Fi 7 and dual USB4 ports that the G3 Pro lacks entirely. Buyers who need real desktop-replacement performance for creative or office multitasking should choose the Geekom GT1 Mega Ultra 9, while shoppers who just want the cheapest usable Windows box should pick the GMKtec NucBox G3 Pro (16GB + 512GB).
