Can the AMD Instinct MI325X run S4?

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

FP16 yes 3563k 7590.4-9277.1 t/s ~50.6-61.8 (slow)
Q8 yes 3567k 15180.7-18554.2 t/s ~101.2-123.7 (slow)
Q4 yes 3569k 27108.4-33132.5 t/s ~180.7-220.9 (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.

FAQ

Can the AMD Instinct MI325X run S4?โ–ถ

Yes. At Q4 it generates ~27108.4-33132.5 tok/s and fits up to 3569k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~180.7-220.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3569k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
