FP16 yes 1082k 2004.5-2388.9 t/s ~23.9-28.5 (slow)
Q8 yes 1091k 4009-4777.9 t/s ~47.9-57 (slow)
Q4 yes 1095k 7159-8531.9 t/s ~85.5-101.9 (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 H100 SXM5 80GB run mBART-50?โ–ถ

Yes. At Q4 it generates ~7159-8531.9 tok/s and fits up to 1095k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~85.5-101.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1095k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
