Can the NVIDIA H200 run gpt-sw3-40b?
Yes — here's how fast and up to what context, with real measured numbers.
gpt-sw3-40b on the NVIDIA H200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 147k | 43.8-52.2 t/s | ~0.4-0.4 (slow) |
| Q8 | yes | 269k | 87.6-104.4 t/s | ~0.7-0.9 (slow) |
| Q4 | yes | 323k | 156.4-186.4 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 H200 run gpt-sw3-40b?▶
Yes. At Q4 it generates ~156.4-186.4 tok/s and fits up to 323k 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?▶
At Q4, up to about 323k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
