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 H100 SXM5 80GB run Nemotron-H 56B?โ–ถ

Yes. At Q4 it generates ~78-92.9 tok/s and fits up to 124k 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?โ–ถ

At Q4, up to about 124k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
