Can the NVIDIA B200 run DiT-XL/2?
Yes — here's how fast and up to what context, with real measured numbers.
DiT-XL/2 on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2652k | 4325.9-5155.6 t/s | ~21.6-25.8 (slow) |
| Q8 | yes | 2662k | 8651.9-10311.1 t/s | ~43.3-51.6 (slow) |
| Q4 | yes | 2667k | 15449.7-18412.7 t/s | ~77.2-92.1 (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 DiT-XL/2?▶
Yes. At Q4 it generates ~15449.7-18412.7 tok/s and fits up to 2667k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~77.2-92.1 tok/s.
How much context fits?▶
At Q4, up to about 2667k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
