Can the NVIDIA B200 run base LM+GNN+kNN?
Yes — here's how fast and up to what context, with real measured numbers.
base LM+GNN+kNN on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2664k | 10656.9-12700.7 t/s | ~53.3-63.5 (slow) |
| Q8 | yes | 2668k | 21313.9-25401.5 t/s | ~106.6-127 (slow) |
| Q4 | yes | 2670k | 38060.5-45359.7 t/s | ~190.3-226.8 (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 base LM+GNN+kNN?▶
Yes. At Q4 it generates ~38060.5-45359.7 tok/s and fits up to 2670k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~190.3-226.8 tok/s.
How much context fits?▶
At Q4, up to about 2670k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
