Can the AMD Ryzen AI Max+ 395 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 AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1631k | 23.7-29 t/s | ~0.9-1.1 (slow) |
| Q8 | yes | 1683k | 47.4-58 t/s | ~1.9-2.3 (slow) |
| Q4 | yes | 1706k | 84.7-103.5 t/s | ~3.3-4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
