Can the Intel Arc B580 12GB run BigGAN-deep 512x512?

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

BigGAN-deep 512x512 on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 142k 1173.4-1456.7 t/s ~102.9-127.8 (slow)
Q8 yes 144k 2346.9-2913.4 t/s ~205.9-255.6 (slow)
Q4 yes 145k 4190.8-5202.4 t/s ~367.6-456.4 (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 BigGAN-deep 512x512?โ–ถ

Yes. At Q4 it generates ~4190.8-5202.4 tok/s and fits up to 145k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~367.6-456.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 145k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
