Can the AMD Instinct MI455X run Emu2?

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

Emu2 on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1228k 166.9-203.9 t/s ~0.3-0.4 (slow)
Q8 yes 1369k 333.7-407.9 t/s ~0.7-0.8 (slow)
Q4 yes 1431k 595.9-728.4 t/s ~1.2-1.5 (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.

FAQ

Can the AMD Instinct MI455X run Emu2?โ–ถ

Yes. At Q4 it generates ~595.9-728.4 tok/s and fits up to 1431k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.2-1.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1431k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
