Can the NVIDIA B200 run DiffusionGemma 26B-A4B?
Yes — here's how fast and up to what context, with real measured numbers.
DiffusionGemma 26B-A4B on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 470k | 112.3-133.8 t/s | ~0.6-0.7 (slow) |
| Q8 | yes | 569k | 224.6-267.7 t/s | ~1.1-1.3 (slow) |
| Q4 | yes | 613k | 401.1-478 t/s | ~2-2.4 (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 DiffusionGemma 26B-A4B?▶
Yes. At Q4 it generates ~401.1-478 tok/s and fits up to 613k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2-2.4 tok/s.
How much context fits?▶
At Q4, up to about 613k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
