Can the AMD Instinct MI325X run Stable Diffusion XL (SDXL)?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Stable Diffusion XL (SDXL) on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 3467k 555.9-679.4 t/s ~3.7-4.5 (slow)
Q8 yes 3519k 1111.8-1358.8 t/s ~7.4-9.1 (slow)
Q4 yes 3542k 1985.3-2426.5 t/s ~13.2-16.2 (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 Instinct MI325X run Stable Diffusion XL (SDXL)?โ–ถ

Yes. At Q4 it generates ~1985.3-2426.5 tok/s and fits up to 3542k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~13.2-16.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3542k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
