Can the NVIDIA L40S 48GB run ProGen2-xlarge?

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

ProGen2-xlarge on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 228k 49.3-58.7 t/s ~2.3-2.7 (slow)
Q8 yes 277k 98.6-117.5 t/s ~4.6-5.4 (slow)
Q4 yes 298k 176-209.7 t/s ~8.1-9.7 (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 ProGen2-xlarge?โ–ถ

Yes. At Q4 it generates ~176-209.7 tok/s and fits up to 298k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.1-9.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 298k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
