Can the AMD Instinct MI325X run Llama 3.2 90B?

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

Llama 3.2 90B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 173k 21.3-26.1 t/s ~0.1-0.2 (slow)
Q8 yes 444k 42.7-52.1 t/s ~0.3-0.3 (slow)
Q4 yes 563k 76.2-93.1 t/s ~0.5-0.6 (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.

Can the AMD Instinct MI325X run Llama 3.2 90B?โ–ถ

Yes. At Q4 it generates ~76.2-93.1 tok/s and fits up to 563k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.5-0.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 563k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
