Intel Arc A770 16GB vs NVIDIA RTX 3090 for local LLMs
4 reports on the Intel Arc A770 16GB and 165 on the NVIDIA RTX 3090
Which is faster for local LLMs?
On Qwen3.8 27B at 3-bit, the Intel Arc A770 16GB runs at 12.0 tokens per second (one run) and the NVIDIA RTX 3090 at 42.3 (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 NVIDIA RTX 3090 (560 GB/s on the Intel Arc A770 16GB, 936 on the NVIDIA RTX 3090).

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.
