What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Minisforum UM790 Pro
Two whitelisted outlets reviewed this exact model hands-on: Notebookcheck (Ryzen 9 7940HS / Radeon 780M, July 2023) and TechRadar (Aug 2023). Both praise the fast 7940HS, the capable Radeon 780M iGPU, quiet and effective cooling, extensive connectivity (USB4, dual HDMI 2.1, up to four displays) and the compact metal chassis with a bundled VESA mount. Both note the plain design and constrained upgradability; Notebookcheck additionally flags weak 5 GHz Wi-Fi, the lack of an SD card reader, screws awkwardly hidden under the rubber feet, and that the 780M still stops short of a true gaming PC, while TechRadar calls the SSD speeds merely decent. (2 sourced reviews, 2 lab-tested.)
Praised: Fast Ryzen 9 7940HS with strong, sustained multi-core performance; Quiet operation with effective cooling; Extensive connectivity: USB4, dual HDMI 2.1, up to four displays.
Flagged: Plain, unexciting design; Awkward maintenance / limited upgradability (screws hidden under the rubber feet); Radeon 780M still falls short of a true gaming PC.
GMKtec NucBox K8
Only one whitelisted tester, TechRadar, hands-on reviewed the exact base NucBox K8 (Ryzen 7 8845HS). TechRadar calls it the fastest AMD-powered NUC it had tested, praising CPU power, dual M.2 Gen4 slots and dual 2.5GbE LAN at a competitive price, while flagging the all-plastic silver build, awkward internal access and lack of Thunderbolt with only one of the CPU's two USB 4.0 ports exposed. (1 sourced review, 1 lab-tested.)
Praised: Fastest AMD-powered NUC TechRadar had tested; CPU performance beats its Intel Core Ultra 5 comparison; Strong connectivity: dual M.2 PCIe Gen4 slots plus dual 2.5GbE LAN; Competitive price for the performance and features on offer.
Flagged: All-plastic chassis with silver paint that doesn't feel like metal; Awkward internal access to reach RAM and M.2 slots; No Thunderbolt and only one of the CPU's two USB 4.0 ports exposed.
