Can the NVIDIA B200 run Qwen3-8B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen3-8B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1211k | 356.1-424.4 t/s | ~1.8-2.1 (slow) |
| Q8 | yes | 1274k | 712.2-848.8 t/s | ~3.6-4.2 (slow) |
| Q4 | yes | 1301k | 1271.8-1515.7 t/s | ~6.4-7.6 (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 Qwen3-8B?▶
Yes. At Q4 it generates ~1271.8-1515.7 tok/s and fits up to 1301k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.4-7.6 tok/s.
How much context fits?▶
At Q4, up to about 1301k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
