Our take on the GMKtec M3S Intel Core 3 304 Mini PC

The GMKtec NucBox M3S is a small desktop built around Intel's Core 3 304, a 5-core chip (1 performance, 4 efficiency) with a 4.3GHz turbo and 12GB of LPDDR5 memory. It stands out for its connectivity at this size: USB4, two M.2 SSD slots, Wi-Fi 6, 2.5GbE Ethernet and three 4K display outputs over dual HDMI plus USB4. Selectable 15W, 20W and 25W power modes let you trade fan noise for speed. It suits light office work, browsing, media and digital signage; it is not a gaming or heavy-editing machine, and its soldered memory and modest core count put it below pricier mini PCs with upgradeable RAM and stronger CPUs.
