Performance Verdicts

Winner for LLM Inference

tie

Both have 16 GB memory, so bandwidth decides. Microsoft Surface Laptop 7 (15")'s 0 GB/s vs 0 GB/s translates directly to more tokens per second at equivalent model sizes.

Winner for Stable Diffusion / Image Generation

tie

Neither is optimised for image generation, but Microsoft Surface Laptop 7 (15")'s 0 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

tie

Both draw around 999W at peak load.

Overall Winner

Frequently Asked Questions

Q1Which runs Ollama faster — Microsoft Surface Laptop 7 (13.8") or Microsoft Surface Laptop 7 (15")?

Microsoft Surface Laptop 7 (13.8") runs Ollama faster. Its 0 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 0 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?

Microsoft Surface Laptop 7 (13.8") offers better performance-per-dollar for AI workloads due to its 0 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.
