Q8 yes 98k 61.1-72.9 t/s ~0.7-0.9 (slow)
Q4 yes 152k 109.2-130.1 t/s ~1.3-1.6 (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 gpt-sw3-40b?โ–ถ

Yes. At Q4 it generates ~109.2-130.1 tok/s and fits up to 152k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.3-1.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 152k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
