Can the Intel Arc B580 12GB run ProGen2-xlarge?

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

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 ProGen2-xlarge?โ–ถ

Yes. At Q4 it generates ~73.8-91.6 tok/s and fits up to 45k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.5-8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 45k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
