FP16 yes 6037k 40352.9-49320.3 t/s ~82.4-100.7 (slow)
Q8 yes 6039k 80705.9-98640.5 t/s ~164.7-201.3 (slow)
Q4 yes 6040k 144117.6-176143.8 t/s ~294.1-359.5 (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 Hyena-2 153M?โ–ถ

Yes. At Q4 it generates ~144117.6-176143.8 tok/s and fits up to 6040k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~294.1-359.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6040k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
