GMK KB4 a really little mini PC with Ryzen 7 3750H

Today we find another low-consumption and quite powerful mini PC called GMK KB4 and that surprises us with its measurements of only 12.9 x 11.17 x 4.06 cm, really tiny.

Despite its size, inside it hides a powerful motor, since as we read it includes a Ryzen 7 3750H APU, a chip more than enough to even work with design apps or to use it as a mini gaming pc due to the fact that it is capable of moving even 3D games and all emulators. Given its size, we do not have as many connectivity options as we find in larger mini PCs, although we find 3 4K video outputs to highlight.

Standard comes with 16/512 GB and if you want to read more information about the included Ryzen you can read our review of the Beelink SER3 3750H, which is also cheaper.


SoC, RAM and storage

The new GMK KB4 mini PC mounts an AMD Ryzen 7 3750H APU, a Quad Core with Eight threads manufactured in 12nm with Zen 2 processors that reach up to 4 GHz and that includes a powerful Radeon Vega 10 GPU. As a ventilation system, we have a blower who is in direct contact with the APU.

The RAM memory included in a module is 16 GB DDR4 2400MHz, we have another free slot, while for storage we find a 512 GB M.2 2280 SSD unit. Inside this small box, we can also mount another internal 2.5″ SATA 3 storage unit.

Other specs

Regarding wireless connectivity, inside the GMK KB4 we have an Intel-AC 7265 adapter that includes Wi-Fi aC and Bluetooth 4.2. As connectors, we find on the sides of its plastic case 4 USB 3.1 ports, a USB Type-C port with data and video output, 3.5mm audio jack, micro SD card reader that accepts cards up to 128 GB, Gigabit network connector and two HDMI 2.0 video outputs with 4K @ 60 HDR support.

The power supply is external 19V / 3.42A and its hardware is compatible with Windows 10, Windows 11 and Linux.
