Can the Intel Arc B580 12GB run Generative BST?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Generative BST on the Intel Arc B580 12GB

FP16 no โ€” โ€” โ€”
Q8 yes 825 28-34.8 t/s ~2.5-3.1 (slow)
Q4 yes 32k 50.1-62.2 t/s ~4.4-5.5 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the Intel Arc B580 12GB run Generative BST?โ–ถ

Yes. At Q4 it generates ~50.1-62.2 tok/s and fits up to 32k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~4.4-5.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 32k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
