Intel Arc Pro B60 24GB vs M4 Max 128GB for local LLMs

8 reports on the Intel Arc Pro B60 24GB and 52 on the M4 Max 128GB

Which is faster for local LLMs?

On Qwen3.8 27B at 4-bit, the Intel Arc Pro B60 24GB has 22.0 generation tokens/s (3 runs); prompt processing 379.5 tokens/s (2 runs); the M4 Max 128GB has 21.8 generation tokens/s (one run); prompt processing 236.6 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 20% higher on the M4 Max 128GB (456 GB/s on the Intel Arc Pro B60 24GB, 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.

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.
