Can the NVIDIA GeForce RTX 4070 Ti Super run Stable Diffusion XL (SDXL)?
Yes — here's how fast and up to what context, with real measured numbers.
Stable Diffusion XL (SDXL) on the NVIDIA GeForce RTX 4070 Ti Super
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 98k | 72.1-86 t/s | ~4.3-5.1 (slow) |
| Q8 | yes | 150k | 144.3-172 t/s | ~8.6-10.2 (slow) |
| Q4 | yes | 173k | 257.6-307.1 t/s | ~15.3-18.3 (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 Stable Diffusion XL (SDXL)?▶
Yes. At Q4 it generates ~257.6-307.1 tok/s and fits up to 173k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~15.3-18.3 tok/s.
How much context fits?▶
At Q4, up to about 173k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
