Which is faster on Apple M2 Pro: gemma3-12b or gemma3-27b?
This Apple M2 Pro comparison shows VRAM fit and quality data for gemma3-12b vs gemma3-27b, but one or both decode-speed benchmarks are still missing.
Do both models fit on Apple M2 Pro?
gemma3-12b: ✓. gemma3-27b: ✗ No. The fit labels use Q4_K_M VRAM estimates and the benchmark data available for this GPU.
How much VRAM do these models need?
gemma3-12b needs about 7.5GB in Q4_K_M; gemma3-27b needs about 16.5GB 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?
Use the GitHub correction link on this page with your GPU, model, quantization, context length, and measured decode tokens per second.
