Can the AMD Instinct MI325X run IDEFICS-80B?

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

IDEFICS-80B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 226k 23.6-28.9 t/s ~0.2-0.2 (slow)
Q8 yes 470k 47.3-57.8 t/s ~0.3-0.4 (slow)
Q4 yes 577k 84.4-103.1 t/s ~0.6-0.7 (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 IDEFICS-80B?โ–ถ

Yes. At Q4 it generates ~84.4-103.1 tok/s and fits up to 577k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.6-0.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 577k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
