Can the NVIDIA L40S 48GB run Qwen-VLA?

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

Qwen-VLA on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 247k 61.2-73 t/s ~2.8-3.4 (slow)
Q8 yes 286k 122.5-146 t/s ~5.7-6.8 (slow)
Q4 yes 303k 218.7-260.6 t/s ~10.1-12.1 (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 Qwen-VLA?โ–ถ

Yes. At Q4 it generates ~218.7-260.6 tok/s and fits up to 303k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~10.1-12.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 303k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
