Jiutian on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 270k 88-104.8 t/s ~1.1-1.3 (slow)
Q8 yes 355k 175.9-209.7 t/s ~2.1-2.5 (slow)
Q4 yes 393k 314.2-374.4 t/s ~3.8-4.5 (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 Jiutian?โ–ถ

Yes. At Q4 it generates ~314.2-374.4 tok/s and fits up to 393k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.8-4.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 393k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
