Can the NVIDIA B200 run OPT-1.3B?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-1.3B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2633k | 2246.2-2676.9 t/s | ~11.2-13.4 (slow) |
| Q8 | yes | 2653k | 4492.3-5353.8 t/s | ~22.5-26.8 (slow) |
| Q4 | yes | 2661k | 8022-9560.4 t/s | ~40.1-47.8 (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 B200 run OPT-1.3B?▶
Yes. At Q4 it generates ~8022-9560.4 tok/s and fits up to 2661k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~40.1-47.8 tok/s.
How much context fits?▶
At Q4, up to about 2661k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
