In recent years, more powerful mini PCs with desktop-class performance have entered the market, although pricing often remains a drawback.
The GMKtec NucBox K15 mini PC, with OCuLink support, appears to challenge that pattern with a $360 starting price.
This device uses the Intel Core Ultra 5 125U CPU, which offers twelve cores and fourteen threads.
Hybrid CPU architecture and AI acceleration
It uses a hybrid design with 2 performance cores, 8 efficiency cores, and 2 low-power efficiency cores, with a maximum turbo frequency of up to 4.3GHz and 12MB of Intel Smart Cache.
The integrated Intel Graphics GPU reaches a maximum dynamic frequency of 1.85GHz and supports up to 7TOPS for AI workloads.
With the Intel AI Boost NPU, the system delivers up to 21TOPS of AI performance and supports ray tracing along with multi-format hardware encoding and decoding.
