M5 Max 36GB vs NVIDIA RTX Pro 6000 Blackwell for local LLMs

14 reports on the M5 Max 36GB and 71 on the NVIDIA RTX Pro 6000 Blackwell

Which is faster for local LLMs?

On Qwen3.8 27B at 4-bit, the M5 Max 36GB has 22.4 generation tokens/s (2 runs); the NVIDIA RTX Pro 6000 Blackwell has 67.0 generation 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 3.9x higher on the NVIDIA RTX Pro 6000 Blackwell (461 GB/s on the M5 Max 36GB, 1,792 on the NVIDIA RTX Pro 6000 Blackwell).

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.
