Can the NVIDIA B200 run OPT-2.7B (finetuned on PTB)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-2.7B (finetuned on PTB) on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2590k | 1081.5-1288.9 t/s | ~5.4-6.4 (slow) |
| Q8 | yes | 2631k | 2163-2577.8 t/s | ~10.8-12.9 (slow) |
| Q4 | yes | 2649k | 3862.4-4603.2 t/s | ~19.3-23 (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-2.7B (finetuned on PTB)?▶
Yes. At Q4 it generates ~3862.4-4603.2 tok/s and fits up to 2649k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.3-23 tok/s.
How much context fits?▶
At Q4, up to about 2649k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
