Can the NVIDIA B200 run OPT-350M?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-350M on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2662k | 8342.9-9942.9 t/s | ~41.7-49.7 (slow) |
| Q8 | yes | 2667k | 16685.7-19885.7 t/s | ~83.4-99.4 (slow) |
| Q4 | yes | 2669k | 29795.9-35510.2 t/s | ~149-177.6 (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 B200 run OPT-350M?▶
Yes. At Q4 it generates ~29795.9-35510.2 tok/s and fits up to 2669k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~149-177.6 tok/s.
How much context fits?▶
At Q4, up to about 2669k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
