GMKtec has just given a sneak peek of the M6 Ultra, which is set to be an improved version of the standard model released in 2024. The original M6 came equipped with the Ryzen 5 6600H, while the new mini PC will feature the AMD Ryzen 5 7640HS alongside the Radeon 760M.

Enhanced Gaming Performance

The company claims that this processor upgrade will transform the M6 Ultra into a more efficient gaming machine. Although the Radeon 760M isn’t the strongest AMD integrated GPU available, it should be able to run most AAA games smoothly at HD resolution with low settings. For some newer titles, playing at FHD is feasible, but enabling FSR is necessary for a decent gameplay experience.

Impressive Specifications

The Ryzen 5 APU in the M6 Ultra supports up to 256 GB of DDR5 RAM, which operates at 4800 MHz in a dual-channel configuration. In terms of storage, this budget-friendly mini PC is designed with two M.2 slots, allowing for a maximum of 8 TB of PCIe 4.0 storage. Although GMK hasn’t disclosed the full port arrangement, they’ve mentioned that there will be a USB4 port that is fully featured.

This implies that the M6 Ultra is compatible with an external GPU (eGPU) for an enhanced gaming experience (currently, the GMKtec AD-GP1 is priced at $469.99 on Amazon). In addition to this, GMK has indicated that the mini PC will come with dual 2.5G Ethernet, HDMI 2.0, and DisplayPort 1.4 ports. Other impressive features highlighted in the teaser include a dual-fan cooling system, WiFi 6, and the ability to support triple-display output.

Pricing and Release Date

As for the cost, GMKtec hasn’t disclosed the exact price for the M6 Ultra in China, but it is described as a “AAA gaming powerhouse priced under 1,000 yuan.” This implies that the launch price in the Chinese market will be roughly around $140. More information will be shared on August 15, 2025.
