GMKTech K8 Nucbox Mini PC Revew – With Ryzen 8845HS Processor

My latest review is of the GMKtec K8 “NucBox” Mini PC, featuring a Ryzen 8845HS processor. Priced around $649—with potential discounts available on platforms like Amazon—this mini PC merges notable performance with a compact form factor. But it has some shortcomings in networking and USB 4.0 performance.

Upon unboxing, I found the K8 to lack the metal design of some of the other Mini PC’s we’ve looked at lately. However, the real appeal of this device lies beneath its modest exterior. Equipped with that Ryzen processor, 32 GB of DDR5 5600 RAM, upgradable to 64 GB, and a 1 TB NVMe SSD with room for expansion, the K8 provides great performance for its price point.

Connectivity options on the K8 are similar to other Mini PCs, with a mix of USB 4.0, USB 3, and USB 2 ports, alongside dual 2.5 Gb Ethernet ports and multiple video output choices. However, during my testing, I encountered issues in the performance disparities between the Ethernet ports and found the USB 4.0 port’s throughput to fall short of its advertised 40 Gb/s capability.

The K8 comes with an activated copy of Windows 11 Pro. Like many PC makers, GMKTec found a loophole in the Microsoft licensing process which means that you will only be allowed to create a local account when first booting up.

The K8 proved itself as a capable for video editing, handling a simple 4K 60fps project effectively without any hiccups or lag running DaVinci Resolve.

Gaming on the K8 was a pleasant surprise; titles like Red Dead Redemption 2 and No Man’s Sky ran well at 1080p, showcasing the integrated GPU’s capabilities. While we couldn’t hit consistent 60 FPS rates, most games are comfortably over 30. Emulation performance was equally impressive, with the Dolphin Emulator running demanding titles at full frame rates.

Benchmarking further validated the K8’s performance credentials, positioning it alongside more expensive systems from just a few years ago equipped with dedicated GPUs. The stress test results showed minimal thermal throttling under load, though fan noise became noticeable during intensive tasks.

The K8’s versatility extends to Linux compatibility, with my tests on Ubuntu showing excellent hardware support out of the box. This adaptability makes the K8 a suitable candidate for a range of applications including home labs.

While the K8 may not be the perfect fit for users with high throughput demands for external storage and networking, its performance, upgradability, and competitive pricing make it a decent option for a variety of users. As with any purchase in this category, prospective buyers should weigh the balance of performance, price, and potential compromises to determine if the K8 meets their specific needs and expectations.
