Can the NVIDIA GeForce RTX 4070 Ti Super run GPT-2 (1.5B)?
Yes — here's how fast and up to what context, with real measured numbers.
GPT-2 (1.5B) on the NVIDIA GeForce RTX 4070 Ti Super
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 156k | 163.5-194.9 t/s | ~9.7-11.6 (slow) |
| Q8 | yes | 179k | 327-389.8 t/s | ~19.5-23.2 (slow) |
| Q4 | yes | 189k | 584-696 t/s | ~34.8-41.4 (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 GeForce RTX 4070 Ti Super run GPT-2 (1.5B)?▶
Yes. At Q4 it generates ~584-696 tok/s and fits up to 189k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~34.8-41.4 tok/s.
How much context fits?▶
At Q4, up to about 189k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
