Can the Instinct MI455X run Command R+?

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

Command R+ on the Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 574k 59.4-72.6 t/s ~0.1-0.1 (slow)
Q8 yes 891k 118.7-145.1 t/s ~0.2-0.3 (slow)
Q4 yes 1031k 212-259.1 t/s ~0.4-0.5 (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 Instinct MI455X run Command R+?โ–ถ

Yes. At Q4 it generates ~212-259.1 tok/s and fits up to 1031k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1031k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
