Can the AMD Radeon RX 9070 XT run Stable Diffusion (LDM-KL-8-G)?
Yes — here's how fast and up to what context, with real measured numbers.
Stable Diffusion (LDM-KL-8-G) on the AMD Radeon RX 9070 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 157k | 139.9-171 t/s | ~8.7-10.6 (slow) |
| Q8 | yes | 180k | 279.8-342 t/s | ~17.4-21.2 (slow) |
| Q4 | yes | 189k | 499.7-610.7 t/s | ~31-37.9 (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 AMD Radeon RX 9070 XT run Stable Diffusion (LDM-KL-8-G)?▶
Yes. At Q4 it generates ~499.7-610.7 tok/s and fits up to 189k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~31-37.9 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.
