Can the NVIDIA GeForce RTX 3080 Ti run Cosmos-Reason1 7B?
Yes — here's how fast and up to what context, with real measured numbers.
Cosmos-Reason1 7B on the NVIDIA GeForce RTX 3080 Ti
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 19k | 95.1-113.3 t/s | ~4.2-5 (slow) |
| Q4 | yes | 43k | 169.8-202.4 t/s | ~7.4-8.9 (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 GeForce RTX 3080 Ti run Cosmos-Reason1 7B?▶
Yes. At Q4 it generates ~169.8-202.4 tok/s and fits up to 43k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~7.4-8.9 tok/s.
How much context fits?▶
At Q4, up to about 43k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
