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
(M4, 2024) winsNeither is optimised for image generation, but Apple Mac Mini (M4, 2024)'s 120 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
(M4, 2024) winsApple Mac Mini (M4, 2024) draws 20W at peak vs 45W — a 25W difference. Running AI workloads 12 hours/day, that's roughly 110 kWh saved per year. For always-on inference, Apple Mac Mini (M4, 2024) has meaningfully lower operating costs.
Overall Winner
(M4, 2024) winsApple Mac Mini (M4, 2024) 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 — Apple Mac Mini (M4, 2024) or GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5)?
Apple Mac Mini (M4, 2024) runs Ollama faster. Its 120 GB/s memory bandwidth vs 68 GB/s means faster token generation — roughly 1.8× more tokens/second on the same model. On Llama 3.1 8B, expect around 4 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?
Apple Mac Mini (M4, 2024) offers better performance-per-dollar for AI workloads due to its 120 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?
Apple Mac Mini (M4, 2024) on macOS benefits from the best Ollama experience — zero configuration, Metal backend, and seamless model management. GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB DDR5) on Windows has broader x86 compatibility but less mature iGPU AI acceleration.
