The mini PC market has evolved rapidly, and Gmktec is clearly aiming to raise the bar with its latest release, the Gmktec NucBox K16. Designed for creators, professionals, and enthusiasts who want serious desktop-class power in a compact form factor, the NucBox K16 combines AMD’s proven Ryzen performance with modern connectivity options like USB4 and OCuLink. This mini PC positions itself as a flexible solution for productivity, content creation, and even light gaming, without taking up much desk space.
At the heart of the NucBox K16 is the AMD Ryzen 7 7735HS processor, built on AMD’s efficient Zen 3+ architecture. With 8 cores and 16 threads and boost clocks reaching up to 4.75GHz, the processor delivers smooth performance for multitasking, video editing, software development, and other demanding workloads. It feels responsive even under sustained load, making it suitable for users who need consistent performance throughout the day.
The integrated Radeon 680M GPU, clocked at up to 2200MHz, handles everyday graphics tasks with ease. It supports light to moderate gaming, smooth 4K media playback, and GPU-accelerated creative applications. While it is not meant to replace a dedicated graphics card, the performance is impressive for an integrated solution and more than enough for most productivity-focused users.
The mini PC comes equipped with 32GB of LPDDR5X memory running at 6400MT/s. This high-speed memory ensures quick app launches, smooth multitasking, and improved overall system responsiveness. Since the memory is soldered, it cannot be upgraded later, but the included 32GB should be sufficient for most professional use cases.
Storage is one of the strong points of the NucBox K16. It supports two PCIe 4.0 x4 M.2 2280 SSDs with a combined capacity of up to 16TB. Out of the box, it ships with either a 512GB or 1TB SSD. This setup allows users to expand storage significantly, making it ideal for large media libraries, project files, or development environments.
Gmktec has equipped the NucBox K16 with a full-featured USB4 port offering up to 40Gbps data transfer speeds. It also supports DisplayPort 1.4 output with up to 8K at 60Hz and 100W power delivery. The inclusion of an OCuLink port is a standout feature, enabling external GPU connectivity with up to 64Gbps of PCIe Gen4 bandwidth. This opens the door for users who want to pair the mini PC with a powerful external graphics card.
The front panel includes two USB 3.2 Gen 2 ports, a USB4 Type-C port, a 3.5mm audio jack, the OCuLink connector, and the power button. On the rear, users get two more USB 3.2 Gen 2 ports, HDMI, DisplayPort, two 2.5GbE LAN ports, and the DC power input. The system supports up to three simultaneous displays, making it suitable for multi-monitor productivity setups.
The CNC-machined aluminum chassis gives the NucBox K16 a premium look and feel. Despite its compact size of 107 x 111 x 56 mm, the internal design includes dual fans, copper heat pipes, and a well-planned airflow system. This cooling solution helps maintain stable performance while keeping noise levels under control during heavy workloads.
The Gmktec NucBox K16 officially goes on sale on January 20, 2026. The configuration with 32GB RAM and a 512GB SSD is priced at $679.99, while the 1TB SSD variant costs $729.99. These launch prices are discounted from the original MSRPs of $899.99 and $949.99, making the initial offering particularly attractive for early buyers.

Compared to earlier mini PCs such as the Gmktec M6 Ultra Mini PC, the Gmktec NucBox K16 delivers a strong balance of performance and efficiency. The Ryzen 7 7735HS handles demanding applications smoothly, whether it’s video rendering, coding, or running multiple virtual desktops. Everyday tasks feel instant, and the system remains responsive even when pushed harder.
Thermal management is another area where the K16 performs well. The dual-fan setup and copper heat pipes keep temperatures in check without excessive noise, which is important for users working in quiet environments. Connectivity is also a major highlight, especially the inclusion of USB4 and OCuLink, which adds future-proofing and flexibility rarely seen in mini PCs at this size.
The only real limitation comes from the non-upgradeable RAM. While 32GB is generous, power users who prefer modular upgrades may see this as a drawback. Still, for most users, the overall experience is polished, reliable, and clearly aimed at serious workloads rather than casual use.
For readers considering more affordable options, Gmktec also offers capable alternatives like the Gmktec NucBox K15 Mini PC and the Gmktec NucBox M5 Ultra, which are better suited for lighter workloads or users with different connectivity requirements.
If you are looking for a compact yet powerful PC for creative work, development, or multitasking-heavy workloads, the Gmktec NucBox K16 is a compelling choice. Its strong CPU performance, modern ports, and external GPU support make it more versatile than many competitors in the mini PC segment. Users who value upgradability may need to consider the fixed memory, but for most professionals, the configuration is more than sufficient.
The Gmktec NucBox K16 stands out as a well-rounded high-performance mini PC that delivers desktop-level capabilities in a remarkably small package. With a powerful Ryzen processor, premium build quality, and forward-looking connectivity options, it offers excellent value at its launch price. For creators and power users who want performance without the bulk of a traditional desktop, the NucBox K16 is an easy recommendation.
