This GMKTec K12 vs K15 mini PC comparison breaks down performance, efficiency, gaming, and real-world workloads to help you decide which is the better buy. Both systems feature OCuLink, USB4, dual 2.5GbE, and expandable storage, but use very different CPUs—AMD Ryzen 7 vs Intel Core Ultra 5. I test Cinebench, Geekbench, GPU performance, gaming benchmarks, and productivity workloads to see how they stack up. You’ll also see power consumption, noise levels, and external GPU scaling with OCuLink. If you’re shopping for a mini PC for gaming, content creation, or everyday use, this review will help you choose the right system.
