Gmktec has carved out a niche in the mini PC market, offering compact yet powerful solutions for users who want desktop-grade performance in a small form factor. Its latest release, the M6 Ultra Mini PC, brings together AMD’s latest Ryzen 5 7640HS processor, Radeon 760M integrated graphics, and support for up to 128GB of DDR5 RAM. Positioned as an affordable yet versatile machine, the M6 Ultra is designed for gamers, content creators, and professionals seeking a space-saving but high-performance computing solution.

Gmktec M6 Ultra Mini PC Features

Compact Yet Capable Design

The M6 Ultra measures just 128.8 × 127 × 47.8 mm, making it smaller than most desktop setups but still packed with serious hardware. Its compact footprint allows it to fit seamlessly into offices, entertainment centers, or even mobile setups without sacrificing functionality.

Ryzen 5 7640HS Processor

At the core, the M6 Ultra runs on AMD’s Ryzen 5 7640HS, built on the Zen 4 architecture with TSMC’s 4nm process. The chip features six cores and twelve threads, reaching up to 5.0 GHz boost clock, supported by 22 MB of cache. With a 50W TDP, it balances strong performance with stable thermal efficiency, making it ideal for multitasking and demanding workloads.

Radeon 760M Graphics

For graphics, the M6 Ultra integrates the AMD Radeon 760M GPU with RDNA 3 architecture. With eight cores clocked at up to 2600 MHz, the GPU rivals Nvidia’s GTX 1650 Ti in performance. Benchmark tests highlight its capabilities:

  • Forza Horizon 5: 65–96 FPS (Medium settings)
  • Genshin Impact: 54–68 FPS
  • Cyberpunk 2077: 47–63 FPS (Low settings)
  • The Witcher 3: 40–68 FPS

This makes the M6 Ultra capable of casual to mid-tier gaming and multimedia workloads.

Memory & Storage

The mini PC supports up to 128GB DDR5 RAM at 4800 MT/s via dual SO-DIMM slots, ensuring future-proof memory capacity. Storage expansion is generous, with dual M.2 PCIe 3.0 ×4 SSD slots, each supporting up to 8TB capacity. Gmktec has also integrated a tool-free quick-release system, making upgrades straightforward for users.

Cooling System

To maintain stable performance, the M6 Ultra uses a dual-fan cooling setup—one fan dedicated to the CPU and the other ensuring airflow for RAM and SSDs. This design improves thermal stability and reduces noise, even under heavy loads.

The M6 Ultra is loaded with modern connectivity features:

  • Wi-Fi 6E & Bluetooth 5.2
  • USB 4.0 port (40Gbps, 100W PD input, external GPU dock support)
