GMK’s first mini PC with an AMD Ryzen 9 7940HS processor is now available for purchase from GMK’s website, AliExpress, or Amazon.

The GMK K4 is a 123 x 112 x 43.2mm (4.84″ x 4.41″ x 1.7″) computer with a metal chassis and the most powerful mobile chip in AMD’s “Phoenix” range.

We first learned in April that GMK was working on a mini PC with AMD Phoenix chips, and now it looks like the first model is here… but there may be more on the way. Earlier reports had indicated that there would be versions with Ryzen 7 7840HS chips, for example, but GMK is only selling the Ryzen 9 model so far.

Prices and configuration options vary from store to store. Here are starting prices/configs as of June 27, 2023:

Note that these prices reflect “flash sale” pricing, and may go up over time.

For now, the GMK website has the lowest pricing: a model with 32GB of RAM and 1TB of storage costs $690 from GMK, $700 from Amazon, and $730 from AliExpress.

Meanwhile, the AliExpress listing offers the most configuration options: you can opt for 16GB, 32GB, or 64GB of memory.

All models are powered by AMD’s Ryzen 9 7940HS processor, which features:

  • CPU architecture: Zen 4
  • Cores / Threads: 8  / 16
  • CPU freq: 4 GHz base / 5.2 GHz max boost
  • Cache: 20MB
  • GPU: Radeon 780M
  • GPU architecture: 12 RDNA 3 compute units
  • GPU freq: Up to 2.8 GHz
  • TDP: 35 – 54W

The computer has two SODIMM slots for up to 64GB of total DDR5-5600 memory and a PCIe Gen 4×4 connector for NVMe solid state drives.

Ports include:

  • 2 x HDMI 2.1
  • 1 x USB4 Type-C (w/40 Gbps data and DisplayPort 1.4 Alt Mode)
  • 3 x USB 3.2 Type-A
  • 1 x USB 2.0 Type-A
  • 1 x 2.5 GbE Ethernet
  • 1 x 3.5mm audio combo

The computer also has an AMD RZ608 wireless card with WiFi 6 and Bluetooth 5.2 support, a cooling system that includes a fan for active cooling and dual copper heat pipes, and a quick release panel that should make it fairly easy to upgrade or replace memory and storage.

  1. 1 x USB4 Type-C (w/40 Gbps data and DisplayPort 1.4 Alt Mode)
    1 x 2.5 GbE Ethernet

    1.4 Alt Mode and 1 Lan port? Better but still weak

  2. This is really a nice product for traveler or people with small space. Now if you can design a monitor that can be rolled and assembled in a frame, it would be awesome.
