Intel Arc Pro B70 vs AMD Radeon AI PRO R9700 32GB for local LLMs

14 reports on the Intel Arc Pro B70 and 43 on the AMD Radeon AI PRO R9700 32GB

Which is faster for local LLMs?

On Qwen3.6 35B · 3B active at 4-bit, the Intel Arc Pro B70 runs at 63.7 tokens per second (5 runs) and the AMD Radeon AI PRO R9700 32GB at 61.4 (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 5% higher on the AMD Radeon AI PRO R9700 32GB (608 GB/s on the Intel Arc Pro B70, 640 on the AMD Radeon AI PRO R9700 32GB). Across the 2 models both have been measured on, the Intel Arc Pro B70's median is higher on 1 and the AMD Radeon AI PRO R9700 32GB'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
