M2 Max 64GB vs NVIDIA Tesla P40 24GB for local LLMs
4 reports on the M2 Max 64GB and 8 on the NVIDIA Tesla P40 24GB
Which is faster for local LLMs?
On Qwen3.6 35B · 3B active at 4-bit, the M2 Max 64GB runs at 71.3 tokens per second (one run) and the NVIDIA Tesla P40 24GB at 9.7 (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 18% higher on the M2 Max 64GB (410 GB/s on the M2 Max 64GB, 346 on the NVIDIA Tesla P40 24GB).

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.
