Can the AMD Instinct MI300X 192GB run Stable Cascade?

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

Stable Cascade on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1258k 326.1-398.5 t/s ~2.5-3 (slow)
Q8 yes 1297k 652.1-797.1 t/s ~4.9-6 (slow)
Q4 yes 1314k 1164.6-1423.3 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 MI300X 192GB run Stable Cascade?โ–ถ

Yes. At Q4 it generates ~1164.6-1423.3 tok/s and fits up to 1314k 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 1314k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
