M4 Max 64GB vs NVIDIA RTX Pro 6000 Blackwell for local LLMs
18 reports on the M4 Max 64GB and 70 on the NVIDIA RTX Pro 6000 Blackwell
Which is faster for local LLMs?
On Gemma 4 31B at 4-bit, the M4 Max 64GB has 22.4 generation tokens/s (one run); prompt processing 62.7 tokens/s (one run); the NVIDIA RTX Pro 6000 Blackwell has 51.0 generation tokens/s (one run); prompt processing 15359.0 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 3.3x higher on the NVIDIA RTX Pro 6000 Blackwell (546 GB/s on the M4 Max 64GB, 1,792 on the NVIDIA RTX Pro 6000 Blackwell). Across 2 shared models with generation measurements on both cards, the M4 Max 64GB's median is higher on 0 and the NVIDIA RTX Pro 6000 Blackwell's on 2.

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.
