Gmktec launches the compact M6 Ultra mini PC
Gmktec has unveiled the M6 Ultra mini PC in China, a pocket-sized system targeting power users, content creators and light gamers. Sales begin August 19, with a promotional barebone price of 1499 yuan (about $210). Configured SKUs include a 16GB RAM + 512GB SSD model at 1999 yuan ($280) and a higher-end 32GB RAM + 1TB SSD version for 2499 yuan ($350).
Key specifications and hardware
Processor and memory
The M6 Ultra measures a compact 128.8 × 127 × 47.8 mm and is powered by AMD's Ryzen 5 7640HS. Built on the Zen 4 architecture and TSMC’s 4nm node, the CPU offers six cores, 12 threads, a boost clock up to 5.0 GHz and about 22 MB combined cache. Gmktec configures the platform at a 50W TDP to balance sustained performance and thermals for multitasking and productivity workloads.
Graphics and gaming performance
Graphics are handled by an integrated AMD Radeon 760M GPU, leveraging RDNA 3 architecture with eight compute units clocking up to 2.6 GHz. Gmktec positions the 760M as roughly comparable to an Nvidia GTX 1650 Ti. Real-world benchmarks shared by the company show Forza Horizon 5 running at 65–96 FPS on medium settings, Genshin Impact at 54–68 FPS, Cyberpunk 2077 at 47–63 FPS on low settings, and The Witcher 3 averaging 40–68 FPS — numbers that make the M6 Ultra a solid option for 1080p play and creative apps that rely on GPU acceleration.
Memory, storage and expandability
The mini PC supports up to 128GB of DDR5 at 4800 MT/s across two SO-DIMM slots. Dual M.2 PCIe 3.0 ×4 slots enable fast NVMe storage and accept drives up to 8TB each. Gmktec includes a tool-free quick-release mechanism to simplify upgrades, catering to users who want to swap memory or SSDs without fuss.
Cooling, connectivity and display options
Cooling is handled by a dual-fan design: one fan dedicated to the CPU and another optimizing airflow across SSDs and RAM. This split arrangement improves thermal stability while keeping acoustic noise low under sustained loads. Networking is robust with dual 2.5G Ethernet ports, Wi-Fi 6E and Bluetooth 5.2. A USB4 port delivers 40 Gbps transfer speeds, supports 100W PD input and external GPU docks. Additional I/O includes HDMI, DisplayPort, USB 3.2 Gen2, USB 2.0 and a 3.5mm audio jack. The system can drive up to three displays with a combined output up to 8K resolution.
Comparisons, advantages and use cases
Compared with other compact mini PCs, the M6 Ultra stands out for its balance of CPU performance, RDNA 3 graphics and large DDR5 memory support — up to 128GB, which is rare in this category. It competes with both integrated-graphics Intel mini PCs and discrete-GPU small form-factor machines, offering a cost-effective option for developers, creators, home labs and casual gamers who need a powerful, upgradeable small desktop. For users needing higher single-thread or specific Intel-optimized workloads, Gmktec's own NucBox M3 Ultra with an Intel Core i7-12700H remains an alternative, especially if triple 4K display output is a priority.
Market relevance and final thoughts
The M6 Ultra arrives at a competitive price point and is well suited for professionals who want a compact workstation, streamers and gamers targeting 1080p performance, and IT pros building compact nodes for edge deployments. With modern connectivity, tool-less upgrades and a respectable thermals package, it’s a persuasive entry in the mini PC market — especially for buyers who prioritize DDR5 memory capacity and upgradable storage.
