Can the NVIDIA L40S 48GB run BigGAN-deep 512x512?

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

BigGAN-deep 512x512 on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 648k 2798.4-3335 t/s ~129.6-154.4 (slow)
Q8 yes 649k 5596.7-6670.1 t/s ~259.1-308.8 (slow)
Q4 yes 650k 9994.1-11910.8 t/s ~462.7-551.4 (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 NVIDIA L40S 48GB run BigGAN-deep 512x512?โ–ถ

Yes. At Q4 it generates ~9994.1-11910.8 tok/s and fits up to 650k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~462.7-551.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 650k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
