Gmktec has launched the NucBox K15, a compact Mini PC powered by Intel’s new Core Ultra 5 125U processor. The system targets users who need high-efficiency performance for productivity, AI workloads, and flexible expansion. It also supports external GPU setups via OCuLink, positioning it as a small but capable alternative to traditional desktop systems.
Gmktec NucBox K15 Specifications
The Core Ultra 5 125U features a 12-core, 14-thread design that combines performance, efficiency, and low-power cores. It supports a turbo boost frequency of up to 4.3GHz and a configurable TDP that scales up to 35W.
Gmktec pairs this with Intel Arc integrated graphics and the Intel AI Boost NPU, enabling the system to reach up to 21 TOPS of INT8 AI performance. The platform is capable of handling light gaming, 4K and 8K video playback, AI inference, and creative tasks such as editing and development.
In benchmarks, the system scores between 3,500 and 4,500 points in 3DMark Time Spy and exceeds 1.1 million in the Master Lu benchmark. These numbers place it among the top performers in the low-power Mini PC segment.
The NucBox K15 supports up to 96GB of dual-channel DDR5-4800 RAM and includes three M.2 2280 PCIe 4.0 SSD slots, allowing for a total storage capacity of up to 24TB.
In terms of connectivity, the device features a full-featured USB4 port that delivers 40Gbps bandwidth and supports 100W power input, DisplayPort 1.4 video output, and data transfer. The system also includes HDMI 2.1, DisplayPort 1.4, dual 2.5Gb Ethernet ports, Wi-Fi 6E, and Bluetooth 5.2. It can support up to four 4K displays at once, along with 8K output at 60Hz.
The rear-mounted OCuLink interface allows users to connect external GPUs using PCIe Gen4 x4 bandwidth. With compatible Nvidia RTX 40 or 50-series cards, the NucBox K15 can be converted into a gaming or rendering workstation.
The Mini PC ships with Windows 11 and also supports Linux distributions such as Ubuntu. For cooling, a dual-fan system with copper heat pipes manages thermal performance during sustained workloads. The system operates at a low 15W base power draw and scales up to 35W for more demanding tasks.
