Can the AMD Instinct MI325X run DBRX?

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

Q8 yes 311k 28.6-35 t/s ~0.2-0.2 (slow)
Q4 yes 489k 51.1-62.5 t/s ~0.3-0.4 (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 DBRX?โ–ถ

Yes. At Q4 it generates ~51.1-62.5 tok/s and fits up to 489k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 489k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
