Eight Ryzen cores against four Intel ones is the headline here, and the Geekom A6 (Ryzen 7 16GB + 1TB) turns that into a win on every column the two share: a higher owner rating, a three-year warranty against one year, DDR5 memory instead of DDR4, and double the RAM and storage of the GMKtec NucBox G3S (8GB + 256GB). Its Ryzen 7 6800H and Radeon 680M graphics handle office multitasking, media and light creative work with room to spare, and the USB4 port plus dual HDMI can drive up to four displays, well beyond what the GMKtec NucBox G3S (8GB + 256GB)'s two HDMI ports support. The GMKtec NucBox G3S (8GB + 256GB) still has a place as the far cheaper option for anyone who just needs a browser and a word processor. Choose the Geekom A6 (Ryzen 7 16GB + 1TB) for a genuine multi-monitor desktop replacement, and choose the GMKtec NucBox G3S (8GB + 256GB) to spend as little as possible on a working Windows machine.
