Can the AMD Instinct MI455X run APUS-xDAN-4.0(MoE)?

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

APUS-xDAN-4.0(MoE) on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 378k 45.4-55.5 t/s ~0.1-0.1 (slow)
Q8 yes 793k 90.8-111 t/s ~0.2-0.2 (slow)
Q4 yes 976k 162.1-198.2 t/s ~0.3-0.4 (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 APUS-xDAN-4.0(MoE)?โ–ถ

Yes. At Q4 it generates ~162.1-198.2 tok/s and fits up to 976k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 976k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
