Can the NVIDIA H200 run S4?
Yes — here's how fast and up to what context, with real measured numbers.
S4 on the NVIDIA H200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1949k | 7036.1-8385.5 t/s | ~58.6-69.9 (slow) |
| Q8 | yes | 1953k | 14072.3-16771.1 t/s | ~117.3-139.8 (slow) |
| Q4 | yes | 1954k | 25129.1-29948.4 t/s | ~209.4-249.6 (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 H200 run S4?▶
Yes. At Q4 it generates ~25129.1-29948.4 tok/s and fits up to 1954k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~209.4-249.6 tok/s.
How much context fits?▶
At Q4, up to about 1954k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
