Spec Comparison
Performance Verdicts
Winner for LLM Inference
32GB DDR5) winsGMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) edges ahead with 32 GB vs 16 GB — enough headroom to run larger quantized models without offloading. GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5)'s 68 GB/s bandwidth also generates tokens faster.
Winner for Stable Diffusion / Image Generation
32GB DDR5) winsNeither is optimised for image generation, but GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5)'s 68 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
32GB DDR5) winsGMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) draws 45W at peak vs 55W — a 10W difference. Running AI workloads 12 hours/day, that's roughly 44 kWh saved per year. For always-on inference, GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) has meaningfully lower operating costs.
Overall Winner
32GB DDR5) winsGMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) 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 M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) or KAMRUI Hyper H2 Mini PC (Intel Core 14450HX)?
GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) runs Ollama faster. Its 68 GB/s memory bandwidth vs 51 GB/s means faster token generation — roughly 1.3× more tokens/second on the same model. On Llama 3.1 8B, expect around 2 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?
GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) offers better performance-per-dollar for AI workloads due to its 68 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.
