Which is faster on Apple M2 Pro: gemma3-4b or llama3.1-8b?
gemma3-4b is faster on Apple M2 Pro in this dataset (75 vs 48 tok/s decode).
Do both models fit on Apple M2 Pro?
gemma3-4b: ✓. llama3.1-8b: ✓. The fit labels use Q4_K_M VRAM estimates and the benchmark data available for this GPU.
How much VRAM do these models need?
gemma3-4b needs about 3GB in Q4_K_M; llama3.1-8b needs about 5GB in Q4_K_M.
Why can speed differ by GPU?
Local LLM speed depends on GPU memory bandwidth, backend, quantization, context length, and whether the model fits entirely in VRAM or unified memory.
How can I correct this comparison?
