Can the NVIDIA H200 run Refact-1.6B?
Yes — here's how fast and up to what context, with real measured numbers.
Refact-1.6B on the NVIDIA H200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1908k | 1095-1305 t/s | ~9.1-10.9 (slow) |
| Q8 | yes | 1932k | 2190-2610 t/s | ~18.3-21.8 (slow) |
| Q4 | yes | 1943k | 3910.7-4660.7 t/s | ~32.6-38.8 (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 Refact-1.6B?▶
Yes. At Q4 it generates ~3910.7-4660.7 tok/s and fits up to 1943k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~32.6-38.8 tok/s.
How much context fits?▶
At Q4, up to about 1943k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
