M1 Pro 32GB vs M4 Max 64GB for local LLMs

2 reports on the M1 Pro 32GB and 18 on the M4 Max 64GB

Which is faster for local LLMs?

On Qwen3.6 35B · 3B active at 4-bit, the M1 Pro 32GB has 25.4 generation tokens/s (one run); prompt processing 38.6 tokens/s (one run); the M4 Max 64GB has 76.4 generation tokens/s (one run); prompt processing 319.9 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 2.7x higher on the M4 Max 64GB (205 GB/s on the M1 Pro 32GB, 546 on the M4 Max 64GB).

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.

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.
