Can the AMD Instinct MI455X run Qwen2-0.5B?

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

Qwen2-0.5B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 6026k 12348-15092 t/s ~25.2-30.8 (slow)
Q8 yes 6034k 24696-30184 t/s ~50.4-61.6 (slow)
Q4 yes 6037k 44100-53900 t/s ~90-110 (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 Qwen2-0.5B?โ–ถ

Yes. At Q4 it generates ~44100-53900 tok/s and fits up to 6037k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~90-110 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6037k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
