Can the NVIDIA L40S 48GB run CPM-Large?

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

CPM-Large on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 572k 121.3-144.6 t/s ~5.6-6.7 (slow)
Q8 yes 611k 242.6-289.1 t/s ~11.2-13.4 (slow)
Q4 yes 629k 433.2-516.3 t/s ~20.1-23.9 (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 CPM-Large?โ–ถ

Yes. At Q4 it generates ~433.2-516.3 tok/s and fits up to 629k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~20.1-23.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 629k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
