Can the NVIDIA L40S 48GB run SANA 1.5 4.8B?

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

SANA 1.5 4.8B on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 504k 65.7-78.3 t/s ~3-3.6 (slow)
Q8 yes 578k 131.4-156.6 t/s ~6.1-7.3 (slow)
Q4 yes 610k 234.6-279.6 t/s ~10.9-12.9 (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 SANA 1.5 4.8B?โ–ถ

Yes. At Q4 it generates ~234.6-279.6 tok/s and fits up to 610k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~10.9-12.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 610k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
