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:
- GMK K4 barebones system with Ryzen 9 7940HS for $519 – GMK
- GMK K4 barebones system with Ryzen 9 7940HS for $520 – AliExpress (clip store coupon)
- GMK K4 w/Ryzen 9 7940HS/32GB/1TB for $700 – Amazon (clip coupon)
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.
- 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 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.
