Can the AMD Instinct MI455X run Llama 3.2 1B?

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

Llama 3.2 1B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 6004k 5019.5-6135 t/s ~10.2-12.5 (slow)
Q8 yes 6023k 10039-12269.9 t/s ~20.5-25 (slow)
Q4 yes 6031k 17926.8-21910.6 t/s ~36.6-44.7 (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 MI455X run Llama 3.2 1B?โ–ถ

Yes. At Q4 it generates ~17926.8-21910.6 tok/s and fits up to 6031k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~36.6-44.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6031k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
