Can the NVIDIA H100 PCIe 80GB run NVIDIA Cosmos 3?
Yes — here's how fast and up to what context, with real measured numbers.
NVIDIA Cosmos 3 on the NVIDIA H100 PCIe 80GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 25k | 22.8-27.2 t/s | ~0.5-0.5 (slow) |
| Q4 | yes | 111k | 40.7-48.5 t/s | ~0.8-1 (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 H100 PCIe 80GB run NVIDIA Cosmos 3?▶
Yes. At Q4 it generates ~40.7-48.5 tok/s and fits up to 111k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.8-1 tok/s.
How much context fits?▶
At Q4, up to about 111k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
