Can the Intel Arc B580 12GB run GPT-2 (774M)?

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

GPT-2 (774M) on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 122k 170.9-212.1 t/s ~15-18.6 (slow)
Q8 yes 134k 341.7-424.2 t/s ~30-37.2 (slow)
Q4 yes 139k 610.2-757.5 t/s ~53.5-66.4 (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 GPT-2 (774M)?โ–ถ

Yes. At Q4 it generates ~610.2-757.5 tok/s and fits up to 139k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~53.5-66.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 139k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
