Can the AMD Instinct MI455X run HiDream-I1?

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

HiDream-I1 on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1373k 343-419.2 t/s ~0.7-0.9 (slow)
Q8 yes 1442k 686-838.4 t/s ~1.4-1.7 (slow)
Q4 yes 1472k 1225-1497.2 t/s ~2.5-3.1 (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 MI455X run HiDream-I1?โ–ถ

Yes. At Q4 it generates ~1225-1497.2 tok/s and fits up to 1472k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.5-3.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1472k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
