GMKtec NucBox M6 Ultra
GMKtec NucBox M6 Ultra combines AMD Ryzen 5 7640HS with integrated Radeon 760M for office multitasking, development and media work. Gaming and GPU-accelerated applications depend on their settings and driver support; the graphics specification alone is not a measured performance result. Replaceable SO-DIMM memory gives it a path for later RAM upgrades. Two Ethernet interfaces are useful for a small home lab, with actual throughput depending on storage and network equipment.
