Mini PCs have long been more than just a second computer - they should be practical, quiet, and at the same time an eye-catcher on the desk. With the NucBox M6 Ultra, GMKtec wants to show that inexpensive and small computers can also impress in everyday use. In the current review, we check whether the mini PC masters the balance between performance, features, and efficiency.

The current review of the NucBox M6 Ultra from GMKtec demonstrates that you don't necessarily need the latest hardware to achieve adequate performance. The biggest advantage of the NucBox M6 Ultra is its price. For just $389 (direct from the manufacturer) or $389 on Amazon, you get a very solid mini PC that has the potential to outperform some of its competitors. Equipped with the AMD Ryzen 5 7640HS, DDR5 RAM, and a fast PCIe SSD, the system proves that compact dimensions and solid performance don't have to be mutually exclusive. Applications start up quickly, multitasking works without noticeable delays, and the device also masters multimedia tasks with ease. Even light creative work and less demanding games are possible with reduced details, which is remarkable for this device size.

An important advantage over many competitors is the support of USB4. This modern standard enables fast data transfer and allows monitors to be connected via DisplayPort or external graphics cards. This sets the GMKtec NucBox M6 Ultra apart from many competing products in its price range. But not everything runs perfectly: under load, the cooling is clearly noticeable acoustically. Although the temperature development remains in the green range, the fan control seems immature and lacks finer tuning. The GMKtec NucBox M6 Ultra is predominantly made of plastic, which means that the feel is not quite as good as devices with an aluminum housing. Nevertheless, the workmanship leaves a solid impression: the housing appears robust, reliably fulfills its purpose, and presents itself in an appealing design.

Despite these weaknesses, the NucBox M6 Ultra primarily impresses with its strong price-performance ratio. For typical home users looking for a compact PC for office, streaming, and everyday tasks, it offers an attractive combination of performance and features. If you can live with the compromises mentioned, you will find a versatile mini PC that easily justifies its place on your desk.
