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 MiniMax-M1-80k?โ–ถ

Yes. At Q4 it generates ~48.4-59.1 tok/s and fits up to 268k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.1-0.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 268k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
