The weirdest one of the bunch is the AMD EPYC 9175F: 16 cores with 512MB of L3 cache! Presumably this is for customers trying to minimize software costs that are based on "per-core" licensing. It really doesn't make much sense to have so few cores at such an expense, otherwise. Does Oracle still use this style of licensing? If so, they need to knock it off.

The only other thing I can think of is some purpose like HFT may need to fit a whole algorithm in L3 for absolute minimum latency, and maybe they want only the best core in each chiplet? It's probably about software licenses, though.
