Spec Comparison
Performance Verdicts
Winner for LLM Inference
Mini PC winsGMKtec NucBox M5 Pro Mini PC wins clearly — 32 GB vs 0 GB means it can fit larger models entirely in memory. Silkland DisplayPort 2.1 Cable (VESA Certified DP80) requires CPU offloading for models above 0 GB, which drops throughput significantly.
Winner for Stable Diffusion / Image Generation
Certified DP80) winsNeither is optimised for image generation, but Silkland DisplayPort 2.1 Cable (VESA Certified DP80)'s 80 GB/s bandwidth makes generation faster. Both run SDXL via Metal (macOS) or ROCm (Linux). Expect slower generation times than a discrete GPU.
Winner for Power Efficiency
Mini PC winsGMKtec NucBox M5 Pro Mini PC draws 45W at peak vs 999W — a 954W difference. Running AI workloads 12 hours/day, that's roughly 4179 kWh saved per year. For always-on inference, GMKtec NucBox M5 Pro Mini PC has meaningfully lower operating costs.
Overall Winner
Certified DP80) winsSilkland DisplayPort 2.1 Cable (VESA Certified DP80) edges ahead overall — better memory, bandwidth, and user ratings for local AI workloads. The gap is real but not always worth the price difference; assess based on your primary use case.

Frequently Asked Questions
Q1Which runs Ollama faster — GMKtec NucBox M5 Pro Mini PC or Silkland DisplayPort 2.1 Cable (VESA Certified DP80)?
Silkland DisplayPort 2.1 Cable (VESA Certified DP80) runs Ollama faster. Its 80 GB/s memory bandwidth vs 51 GB/s means faster token generation — roughly 1.6× more tokens/second on the same model. On Llama 3.1 8B, expect around 3 tok/s vs 2 tok/s.
Q2Can either mini PC run Llama 3 70B?
Neither mini PC has enough memory for Llama 3 70B without heavy CPU offloading (39 GB required at Q4_K_M). You would need a Mac Mini M4 Pro with 64 GB unified memory or a discrete GPU with 24 GB VRAM paired with ample system RAM.
Q3Which is better value for local AI in 2026?
Silkland DisplayPort 2.1 Cable (VESA Certified DP80) offers better performance-per-dollar for AI workloads due to its 80 GB/s bandwidth advantage. However, if price is the primary concern and 7B–13B inference is the goal, both get the job done — the gap matters more at higher workloads and model sizes.
Q4Which has better software support for local AI?
Both run Ollama well. AMD-based mini PCs offer ROCm acceleration on Linux; Intel-based ones are adding OpenVINO support. macOS Apple Silicon has the most polished Ollama experience.
