M5 Max 36GB vs NVIDIA RTX 4070 Ti Super for local LLMs
12 reports on the M5 Max 36GB and 12 on the NVIDIA RTX 4070 Ti Super
Which is faster for local LLMs?
On Qwen3.8 27B at 4-bit, the M5 Max 36GB has 25.8 generation tokens/s (one run); the NVIDIA RTX 4070 Ti Super has 5.7 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 46% higher on the NVIDIA RTX 4070 Ti Super (461 GB/s on the M5 Max 36GB, 672 on the NVIDIA RTX 4070 Ti Super).

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.
