Can the AMD Instinct MI325X run LLaMA-33B?

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

LLaMA-33B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 645k 58.2-71.1 t/s ~0.4-0.5 (slow)
Q8 yes 769k 116.3-142.2 t/s ~0.8-0.9 (slow)
Q4 yes 823k 207.7-253.8 t/s ~1.4-1.7 (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 LLaMA-33B?โ–ถ

Yes. At Q4 it generates ~207.7-253.8 tok/s and fits up to 823k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.4-1.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 823k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
