Can the NVIDIA L40S 48GB run BART-large?

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

BART-large on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 639k 776.2-925.1 t/s ~35.9-42.8 (slow)
Q8 yes 645k 1552.4-1850.1 t/s ~71.9-85.7 (slow)
Q4 yes 647k 2772.1-3303.8 t/s ~128.3-153 (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 BART-large?โ–ถ

Yes. At Q4 it generates ~2772.1-3303.8 tok/s and fits up to 647k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~128.3-153 tok/s.

How much context fits?โ–ถ

At Q4, up to about 647k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
