GMKtec M6 Ultra Review | TechPowerUp

Introduction

GMKtec M6 Ultra is built around AMD’s Ryzen 5 7640HS and DDR5 memory, with hardware that feels like a high-end Mini-PC, including 2.5 GbE network and USB4. With the 32 GB configuration coming in at around $510, it offers solid desktop performance in a compact chassis, without the premium price tag.

AMD’s Ryzen 5 7640HS is a 6-core, 12-thread processor manufactured on TSMC’s 4 nm process and paired with integrated Radeon 760M graphics. This setup delivers plenty of CPU headroom for productivity tasks, media playback, and multitasking. The RDNA 3-based Radeon 760M still stands as the current generation iGPU, making the system great for casual gaming and light graphics work, even though it lags behind Radeon 780M-equipped Mini-PCs, not to mention the newer 890M or Arc 140V graphics.

Connectivity includes two 2.5 GbE LAN ports, Wi-Fi 6E, and a USB4 port with DisplayPort Alt mode support, which is compatible with full-size HDMI and DisplayPort for multiple monitor setups. USB4 also enables high-resolution displays, adding flexibility depending on how the system is being used. Inside, GMKtec leaves room for upgrades, with two DDR5 SODIMM slots and two M.2 NVMe ports available for memory and storage expansion.

The configuration tested here includes 32 GB of DDR5 memory running at 4800 MT/s, paired with an integrated PCIe 3.0 SSD. GMKtec also offers a barebones option for $270 USD without memory, storage, or a pre-installed copy of Windows 11, for users who prefer to use their own components.

I’ll get into the details later in the review, but after spending time with the M6 ​​Ultra, it feels like the kind of Mini-PC that fits most setups. It’s fast enough for everyday work, handles many tasks with ease, and offers more connectivity than most systems in this price range. The integrated graphics are strong enough for casual gaming and simple creative tasks. A few compromises appear, such as the entry-level integrated SSD and high power draw under load, but at around $510, the overall package feels very competitive, especially for anyone looking for a compact Ryzen system with improved flexibility and dual 2.5 GbE connectivity.

That said, let’s dig into it.
