Can the NVIDIA B200 run RWKV-4 World (7B)?
Yes — here's how fast and up to what context, with real measured numbers.
RWKV-4 World (7B) on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1223k | 395-470.7 t/s | ~2-2.4 (slow) |
| Q8 | yes | 1280k | 789.9-941.4 t/s | ~3.9-4.7 (slow) |
| Q4 | yes | 1305k | 1410.6-1681.1 t/s | ~7.1-8.4 (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 RWKV-4 World (7B)?▶
Yes. At Q4 it generates ~1410.6-1681.1 tok/s and fits up to 1305k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~7.1-8.4 tok/s.
How much context fits?▶
At Q4, up to about 1305k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
