Can the NVIDIA B200 run BART-large?
Yes — here's how fast and up to what context, with real measured numbers.
BART-large on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2660k | 7187-8565.3 t/s | ~35.9-42.8 (slow) |
| Q8 | yes | 2666k | 14373.9-17130.6 t/s | ~71.9-85.7 (slow) |
| Q4 | yes | 2669k | 25667.7-30590.3 t/s | ~128.3-153 (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 BART-large?▶
Yes. At Q4 it generates ~25667.7-30590.3 tok/s and fits up to 2669k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~128.3-153 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.
