Llama 3.2 3B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 5944k 1923.4-2350.8 t/s ~3.9-4.8 (slow)
Q8 yes 5993k 3846.7-4701.6 t/s ~7.9-9.6 (slow)
Q4 yes 6014k 6869.2-8395.6 t/s ~14-17.1 (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 MI455X run Llama 3.2 3B?โ–ถ

Yes. At Q4 it generates ~6869.2-8395.6 tok/s and fits up to 6014k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~14-17.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6014k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
