I believe the chiplet links are pretty generous, they handle L3 <-> chiplet traffice and chiplet <-> chiplet traffic. On the smaller configs they use 2 links per chiplet. Thinks like McCalpin do not seem to show much difference on the different number of chiplet Epycs, although I've not personally tested the newest Genoa chips.
