Can the AMD Instinct MI455X run BlenderBot 3?

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

BlenderBot 3 on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 88k 35.3-43.1 t/s ~0.1-0.1 (slow)
Q8 yes 421k 70.6-86.2 t/s ~0.1-0.2 (slow)
Q4 yes 568k 126-154 t/s ~0.3-0.3 (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 BlenderBot 3?โ–ถ

Yes. At Q4 it generates ~126-154 tok/s and fits up to 568k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 568k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
