Can the AMD Instinct MI455X run QwQ-32B?

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

QwQ-32B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1262k 190-232.2 t/s ~0.4-0.5 (slow)
Q8 yes 1386k 379.9-464.4 t/s ~0.8-0.9 (slow)
Q4 yes 1441k 678.5-829.2 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.

Can the AMD Instinct MI455X run QwQ-32B?โ–ถ

Yes. At Q4 it generates ~678.5-829.2 tok/s and fits up to 1441k 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 1441k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
