M4 Pro 64GB vs M5 32GB for local LLMs
33 reports on the M4 Pro 64GB and 3 on the M5 32GB
Which is faster for local LLMs?
On Qwen3 30B · 3B active at 4-bit, the M4 Pro 64GB has 85.9 generation tokens/s (2 runs); prompt processing 793.1 tokens/s (2 runs); the M5 32GB has 57.0 generation tokens/s (one run); prompt processing 1063.0 tokens/s (one run). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 1.8x higher on the M4 Pro 64GB (273 GB/s on the M4 Pro 64GB, 154 on the M5 32GB).

Measured on both
Generation and prompt processing speeds from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same bit class. Each side shows the engines and reported context behind its median. Context can mean a configured window or prompt depth, so these are community comparisons with differing settings. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
