NVIDIA CMP 170HX 64GB (unlocked) vs Intel Arc Pro B70 for local LLMs
10 reports on the NVIDIA CMP 170HX 64GB (unlocked) and 14 on the Intel Arc Pro B70
Which is faster for local LLMs?
On Qwen3.8 27B at 8-bit, the NVIDIA CMP 170HX 64GB (unlocked) runs at 50.0 tokens per second (one run) and the Intel Arc Pro B70 at 16.7 (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 NVIDIA CMP 170HX 64GB (unlocked) (1,493 GB/s on the NVIDIA CMP 170HX 64GB (unlocked), 608 on the Intel Arc Pro B70).

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.
