AMD MI50 32GB vs M2 Max 32GB for local LLMs
13 reports on the AMD MI50 32GB and 3 on the M2 Max 32GB
Which is faster for local LLMs?
On Ornith1.5 35B · 3B active at 4-bit, the AMD MI50 32GB has 108.9 generation tokens/s (one run); the M2 Max 32GB has 108.0 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 2.5x higher on the AMD MI50 32GB (1,024 GB/s on the AMD MI50 32GB, 410 on the M2 Max 32GB).

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.
