Can the Intel Arc B580 12GB run iGPT-L?

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

iGPT-L on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 104k 97.1-120.5 t/s ~8.5-10.6 (slow)
Q8 yes 125k 194.2-241.1 t/s ~17-21.1 (slow)
Q4 yes 134k 346.8-430.5 t/s ~30.4-37.8 (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 iGPT-L?โ–ถ

Yes. At Q4 it generates ~346.8-430.5 tok/s and fits up to 134k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~30.4-37.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 134k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
