// RUN โ€” FITS

Can the AMD Instinct MI455X run Qwen2-Math-1.5B?

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

Qwen2-Math-1.5B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 5996k 4116-5030.7 t/s ~8.4-10.3 (slow)
Q8 yes 6019k 8232-10061.3 t/s ~16.8-20.5 (slow)
Q4 yes 6029k 14700-17966.7 t/s ~30-36.7 (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 Qwen2-Math-1.5B?โ–ถ

Yes. At Q4 it generates ~14700-17966.7 tok/s and fits up to 6029k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~30-36.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6029k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
