FP16 yes 3521k 1153.1-1409.4 t/s ~7.7-9.4 (slow)
Q8 yes 3546k 2306.3-2818.8 t/s ~15.4-18.8 (slow)
Q4 yes 3557k 4118.4-5033.6 t/s ~27.5-33.6 (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.

Can the AMD Instinct MI325X run minChatGPT?โ–ถ

Yes. At Q4 it generates ~4118.4-5033.6 tok/s and fits up to 3557k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~27.5-33.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3557k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
