Can the NVIDIA B200 run Qwen2.5-7B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-7B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1220k | 383.7-457.3 t/s | ~1.9-2.3 (slow) |
| Q8 | yes | 1278k | 767.4-914.6 t/s | ~3.8-4.6 (slow) |
| Q4 | yes | 1304k | 1370.4-1633.2 t/s | ~6.9-8.2 (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 Qwen2.5-7B?▶
Yes. At Q4 it generates ~1370.4-1633.2 tok/s and fits up to 1304k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.9-8.2 tok/s.
How much context fits?▶
At Q4, up to about 1304k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
