Can the AMD Instinct MI325X run mBART-50?

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

mBART-50 on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 3552k 3098.4-3786.9 t/s ~20.7-25.2 (slow)
Q8 yes 3562k 6196.7-7573.8 t/s ~41.3-50.5 (slow)
Q4 yes 3566k 11065.6-13524.6 t/s ~73.8-90.2 (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 mBART-50?โ–ถ

Yes. At Q4 it generates ~11065.6-13524.6 tok/s and fits up to 3566k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~73.8-90.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3566k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
