Intel Arc A770 16GB vs M4 Max 128GB for local LLMs
4 reports on the Intel Arc A770 16GB and 52 on the M4 Max 128GB
Which is faster for local LLMs?
On Qwen3.8 27B at 3-bit, the Intel Arc A770 16GB has 12.0 generation tokens/s (one run); the M4 Max 128GB has 23.9 generation tokens/s (2 runs); prompt processing 249.7 tokens/s (2 runs). 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 about the same on both (560 GB/s on the Intel Arc A770 16GB, 546 on the M4 Max 128GB).

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.
