Can the NVIDIA GeForce RTX 4070 run OPT-2.7B (finetuned on WT2)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-2.7B (finetuned on WT2) on the NVIDIA GeForce RTX 4070
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 63k | 68.1-81.2 t/s | ~5.4-6.4 (slow) |
| Q8 | yes | 104k | 136.3-162.4 t/s | ~10.8-12.9 (slow) |
| Q4 | yes | 122k | 243.3-290 t/s | ~19.3-23 (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 4070 run OPT-2.7B (finetuned on WT2)?▶
Yes. At Q4 it generates ~243.3-290 tok/s and fits up to 122k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.3-23 tok/s.
How much context fits?▶
At Q4, up to about 122k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
