Can the NVIDIA B200 run RWKV-6 (Finch) 3B?
Yes — here's how fast and up to what context, with real measured numbers.
RWKV-6 (Finch) 3B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2578k | 941.9-1122.6 t/s | ~4.7-5.6 (slow) |
| Q8 | yes | 2625k | 1883.9-2245.2 t/s | ~9.4-11.2 (slow) |
| Q4 | yes | 2646k | 3364.1-4009.2 t/s | ~16.8-20 (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-6 (Finch) 3B?▶
Yes. At Q4 it generates ~3364.1-4009.2 tok/s and fits up to 2646k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~16.8-20 tok/s.
How much context fits?▶
At Q4, up to about 2646k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
