Can the NVIDIA H200 run Jiutian?
Yes — here's how fast and up to what context, with real measured numbers.
Jiutian on the NVIDIA H200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 613k | 126-150.2 t/s | ~1.1-1.3 (slow) |
| Q8 | yes | 698k | 252.1-300.4 t/s | ~2.1-2.5 (slow) |
| Q4 | yes | 735k | 450.2-536.5 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 H200 run Jiutian?▶
Yes. At Q4 it generates ~450.2-536.5 tok/s and fits up to 735k 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?▶
At Q4, up to about 735k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
