// RUN โ€” FITS

Can the AMD Instinct MI455X run Command R+?

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

Command R+ on the AMD 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 AMD 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.
