GMKtec NucBox M3 Ultra
GMKtec NucBox M3 Ultra combines Intel Core i7-12700H with integrated Intel Iris Xe (dual-channel memory) 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.
