Can the NVIDIA L40S 48GB run CogVLM-17B?

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

CogVLM-17B on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 33k 18.6-22.1 t/s ~0.9-1 (slow)
Q8 yes 98k 37.1-44.2 t/s ~1.7-2 (slow)
Q4 yes 126k 66.3-79 t/s ~3.1-3.7 (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 CogVLM-17B?โ–ถ

Yes. At Q4 it generates ~66.3-79 tok/s and fits up to 126k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.1-3.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 126k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
