Can the NVIDIA B200 run Tri-21B?
Yes — here's how fast and up to what context, with real measured numbers.
Tri-21B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 510k | 140.9-167.9 t/s | ~0.7-0.8 (slow) |
| Q8 | yes | 589k | 281.7-335.7 t/s | ~1.4-1.7 (slow) |
| Q4 | yes | 624k | 503.1-599.5 t/s | ~2.5-3 (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 Tri-21B?▶
Yes. At Q4 it generates ~503.1-599.5 tok/s and fits up to 624k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.5-3 tok/s.
How much context fits?▶
At Q4, up to about 624k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
