Can the NVIDIA H100 SXM5 80GB run DiffusionGemma 26B-A4B?
Yes — here's how fast and up to what context, with real measured numbers.
DiffusionGemma 26B-A4B on the NVIDIA H100 SXM5 80GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 77k | 47-56 t/s | ~0.6-0.7 (slow) |
| Q8 | yes | 176k | 94.1-112.1 t/s | ~1.1-1.3 (slow) |
| Q4 | yes | 219k | 168-200.2 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 H100 SXM5 80GB run DiffusionGemma 26B-A4B?▶
Yes. At Q4 it generates ~168-200.2 tok/s and fits up to 219k 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 219k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
