Can the NVIDIA B200 run Qwen2.5-14B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-14B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 890k | 198.6-236.7 t/s | ~1-1.2 (slow) |
| Q8 | yes | 979k | 397.3-473.5 t/s | ~2-2.4 (slow) |
| Q4 | yes | 1019k | 709.4-845.5 t/s | ~3.5-4.2 (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 Qwen2.5-14B?▶
Yes. At Q4 it generates ~709.4-845.5 tok/s and fits up to 1019k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.5-4.2 tok/s.
How much context fits?▶
At Q4, up to about 1019k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
