Can the AMD Instinct MI325X run Falcon-40B?

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

Falcon-40B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 470k 47.3-57.8 t/s ~0.3-0.4 (slow)
Q8 yes 592k 94.5-115.5 t/s ~0.6-0.8 (slow)
Q4 yes 646k 168.8-206.3 t/s ~1.1-1.4 (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 Falcon-40B?โ–ถ

Yes. At Q4 it generates ~168.8-206.3 tok/s and fits up to 646k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.1-1.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 646k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
