Frequently Asked Questions
Q1Which runs Ollama faster — GEEKOM IT12 Mini PC (Intel i5-12450H) or OWC Envoy Express Thunderbolt NVMe Enclosure?
GEEKOM IT12 Mini PC (Intel i5-12450H) runs Ollama faster. Its 51 GB/s memory bandwidth vs 0 GB/s means faster token generation — roughly — more tokens/second on the same model. On Llama 3.1 8B, expect around 2 tok/s vs 0 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?
GEEKOM IT12 Mini PC (Intel i5-12450H) offers better performance-per-dollar for AI workloads due to its 51 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.
