GMKtec Mini PC Ryzen 5 7640HS

Best use cases

For a desk where a full-size tower would take up more room than it earns, the GMKtec M6 Ultra puts a Ryzen 5 7640HS, 32GB of DDR5 memory, and a 1TB SSD in a mini PC format. It’s aimed at everyday office work, home use, multitasking, and moderate gaming, with ports for building a multi-display setup rather than relying on a single screen.

Picture a compact workstation with documents on one display, a video call on another, and a browser open on a third. That’s the sort of setup this PC is designed to support. It’s a great fit if you want desktop connectivity without a conventional tower.

Product specs

The processor is an AMD Ryzen 5 7640HS with 6 cores and 12 threads. Graphics are handled by integrated Radeon 760M, so there’s no separate graphics card listed. The 32GB of DDR5 RAM is installed as two 16GB modules, and the 1TB M.2 PCIe 3.0 SSD provides the included storage. The memory can be expanded up to 128GB, the two-slot storage design supports upgrades, but additional memory and drives are not included.

Connections include dual 2.5GbE LAN, Wi-Fi 6, Bluetooth 5.2, USB4, three USB 3.2 Gen 2 ports, one USB 2.0 port, HDMI 2.0, DisplayPort, and a 3.5mm audio jack. The listed display support includes 4K at 60Hz over HDMI and DisplayPort, plus an 8K at 60Hz output through USB4. USB4 also supports power delivery, DisplayPort, and data. Without having tried it, the spec sheet suggests a flexible small desktop, but it doesn’t establish how it performs in a particular game or workload.

Where it shines

The appeal is the combination of a small footprint, generous included memory and storage, and more networking options than a basic home PC usually needs. Dual 2.5GbE ports may matter if you’re setting it up for network-focused tasks, while support for three simultaneous displays gives office multitasking more room to breathe. For a less demanding setup, a simpler mini PC with fewer ports may be enough, this model makes more sense when those connections and the extra screen outputs are useful to you.

The Radeon 760M is described for moderate gaming, and the processor also supports hardware encoding and decoding for AV1, HEVC, and AVC. That makes it relevant for general media and gaming use, but integrated graphics are a real boundary: buyers focused on demanding games should look at a system with dedicated graphics instead. The listed warranty is three years, described as one year of replacement and two years of parts replacement, with coverage terms tied to the stated sales date.

Buying verdict

It may not suit you if high-end gaming performance is the main reason you’re buying a desktop. The M6 Ultra is better judged as a compact work-and-home PC that can also handle moderate gaming, with display and network connections that give it room to serve a more involved setup. If you’ll use the three-display support, dual LAN, or upgrade options, those features help justify choosing it over a more basic mini PC. If you only need a small computer for light everyday tasks, some of that hardware may go unused.
