Can the Instinct MI440X run NVIDIA Cosmos 3?

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

NVIDIA Cosmos 3 on the Instinct MI440X

QuantFits?Max contextSpeedBeyond context
FP16 yes 818k 96.5-117.9 t/s ~0.2-0.2 (slow)
Q8 yes 1013k 192.9-235.8 t/s ~0.4-0.5 (slow)
Q4 yes 1099k 344.5-421.1 t/s ~0.7-0.9 (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 MI440X run NVIDIA Cosmos 3?โ–ถ

Yes. At Q4 it generates ~344.5-421.1 tok/s and fits up to 1099k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.7-0.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1099k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
