// RUN โ€” FITS

Can the Instinct MI440X run Stable Diffusion (LDM-KL-8-G)?

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

Stable Diffusion (LDM-KL-8-G) on the Instinct MI440X

QuantFits?Max contextSpeedBeyond context
FP16 yes 5997k 4257.9-5204.1 t/s ~8.7-10.6 (slow)
Q8 yes 6019k 8515.9-10408.3 t/s ~17.4-21.2 (slow)
Q4 yes 6029k 15206.9-18586.2 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.

Can the Instinct MI440X run Stable Diffusion (LDM-KL-8-G)?โ–ถ

Yes. At Q4 it generates ~15206.9-18586.2 tok/s and fits up to 6029k 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?โ–ถ

At Q4, up to about 6029k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
