Can the NVIDIA L40S 48GB run Nemotron-H 56B?
Yes — here's how fast and up to what context, with real measured numbers.
Nemotron-H 56B on the NVIDIA L40S 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | no | — | — | — |
| Q4 | yes | 34k | 20.1-24 t/s | ~0.9-1.1 (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 Nemotron-H 56B?▶
Yes. At Q4 it generates ~20.1-24 tok/s and fits up to 34k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.9-1.1 tok/s.
How much context fits?▶
At Q4, up to about 34k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
