I recently got in the new GMKTec K8 Plus, a Windows Mini PC powered by a Ryzen 8845HS processor. This system builds on its predecessor, the K8, addressing prior shortcomings such as USB 4 performance and adding new features like an Oculink port for enhanced expandability. You can see more in my latest review.
The price fluctuates quite a bit on this one, so it’s best to visit Amazon for the current best price. Inside, the Mini PC features that 8-core Ryzen processor, 32GB of DDR5 RAM, upgradeable up to 96GB and a 1TB NVME SSD with an open NVME slot for a second drive.
The Oculink port offers direct PCIe connectivity for peripherals, although the current implementation feels a bit experimental due to limited enclosure options. I’ll be working on a video soon demonstrating how the port works with a 4060 GPU. Alongside Oculink, the Mini PC includes two high-performing 40 gigabit USB 4.0 ports with Thunderbolt compatibility. Both worked with my Thunderbolt SSD at its full 2+ gigabyte per second performance.
As for other ports you’ll find dual 2.5Gb Intel i226v Ethernet ports, HDMI and DisplayPort outputs and USB 3.0 and USB 2.0 ports. Using both USB 4.0 ports plus the HDMI and DisplayPort will allow for four display outputs.
Performance testing showcased the Ryzen processor’s capabilities. Everyday tasks, like web browsing and 4K video playback, were super quick and responsive. . The system handled video editing on DaVinci Resolve with ease, provided the workload remained relatively basic. For more demanding projects, the Oculink or Thunderbolt ports could accommodate external GPUs.
Gaming performance was surprisingly solid for a device of this size and price. Titles like Red Dead Redemption 2 and No Man’s Sky were playable at 1080p at lowest settings with frame rates hovering near 60fps. Emulation also performed well, although higher-end systems may be required when looking at PS3 and Xbox 360 games.
Power consumption was efficient, ranging from 13-15 watts at idle to 90 watts under load, with the system maintaining quiet operation throughout. The fan is audible but barely so with a nice low pitched hum that certainly won’t drown out gameplay sounds.
The device also supports Linux, with Ubuntu 24.10 running smoothly during tests with all hardware detected automatically.
Potential buyers should note GMKTec’s limited presence outside China, which could complicate warranty or repair processes. Despite this, the K8 Plus offers an impressive package for its price, especially compared to alternatives like the base model Mac Mini. With double the RAM and significantly larger storage for a lower price, it stands as a versatile and capable Mini PC option for a range of applications.
