Frequently Asked Questions

Q1Which runs Ollama faster — Cable Matters Intel Certified Thunderbolt 5 Cable (3.3ft) or GEEKOM IT12 Mini PC (Intel i5-12450H)?

Cable Matters Intel Certified Thunderbolt 5 Cable (3.3ft) 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?

Cable Matters Intel Certified Thunderbolt 5 Cable (3.3ft) 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.
