AMD MI50 32GB vs Intel Arc Pro B70 for local LLMs

12 reports on the AMD MI50 32GB and 14 on the Intel Arc Pro B70

Which is faster for local LLMs?

On Ornith1.5 35B · 3B active at 4-bit, the AMD MI50 32GB runs at 108.9 tokens per second (one run) and the Intel Arc Pro B70 at 175.3 (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 1.7x higher on the AMD MI50 32GB (1,024 GB/s on the AMD MI50 32GB, 608 on the Intel Arc Pro B70). Across the 2 models both have been measured on, the AMD MI50 32GB's median is higher on 1 and the Intel Arc Pro B70's on 1.

Measured on both

Median tokens per second 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 quant level. Engines and context lengths can still differ between the runs. 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.
