Can the NVIDIA H200 run KataGo?
Yes — here's how fast and up to what context, with real measured numbers.
KataGo on the NVIDIA H200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1956k | 700800-835200 t/s | ~5840-6960 (slow) |
| Q8 | yes | 1956k | 1401600-1670400 t/s | ~11680-13920 (slow) |
| Q4 | yes | 1956k | 2502857.1-2982857.1 t/s | ~20857.1-24857.1 (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 KataGo?▶
Yes. At Q4 it generates ~2502857.1-2982857.1 tok/s and fits up to 1956k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~20857.1-24857.1 tok/s.
How much context fits?▶
At Q4, up to about 1956k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
