Intel Arc B580 runs a 125B AI model nearly three times faster with XeStrata
A test in Japan found XeStrata generated text nearly three times faster than Strata on the same computer.
The comparison used Intel's 12GB Arc B580 graphics card to run a 125-billion-parameter Qwen model.
XeStrata produced 31.1 tokens per second, while Strata produced 10.9.
The test also depended on 64GB of system memory, because the model setup required about 50GB of RAM; the full model was not shown to fit in the card's 12GB of graphics memory.
XeStrata is derived from Strata and includes additional optimisations for supported graphics hardware, but the test did not identify which changes caused the speed difference.
The result shows that inference software can affect text-generation speed without changing the graphics card.
The test measured text generation only, and the reviewer said the card may not suit heavier AI workloads; no further test or next step was given.
PC Watch reported that Intel’s Arc B580 generated text from a 125-billion-parameter AI model at 31.1 tokens per second with XeStrata.
The same computer achieved 10.9 tokens per second with Strata, the project from which XeStrata was derived.
The test used an ASRock Arc B580 Challenger 12GB OC and 64GB of system memory.
The model was Qwen3.8-Flash-Next, configured with IQ3_S quantisation, a 64K-token context and an 8-bit KV cache.
The comparison measured text-generation speed and did not establish that the entire model fit in the graphics card’s 12GB of VRAM.
