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.

Can the AMD Instinct MI300X 192GB run Pixtral Large?โ–ถ

Yes. At Q4 it generates ~48.1-58.8 tok/s and fits up to 323k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 323k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
