Can the AMD Instinct MI455X run Qwen3-Omni-30B-A3B?

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

Qwen3-Omni-30B-A3B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1241k 174.9-213.8 t/s ~0.4-0.4 (slow)
Q8 yes 1376k 349.8-427.5 t/s ~0.7-0.9 (slow)
Q4 yes 1435k 624.6-763.5 t/s ~1.3-1.6 (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 Qwen3-Omni-30B-A3B?โ–ถ

Yes. At Q4 it generates ~624.6-763.5 tok/s and fits up to 1435k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.3-1.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1435k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
