Can the AMD Instinct MI325X run Stable Cascade?

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

Stable Cascade on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1707k 369.1-451.2 t/s ~2.5-3 (slow)
Q8 yes 1746k 738.3-902.3 t/s ~4.9-6 (slow)
Q4 yes 1764k 1318.4-1611.3 t/s ~8.8-10.7 (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 Cascade?โ–ถ

Yes. At Q4 it generates ~1318.4-1611.3 tok/s and fits up to 1764k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.8-10.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1764k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
