The CCDs might be the same but several of the Threadripper models have to be "perfect", e.g. the 7975WX has 32 cores from 4 CCDs:

EPYC 9334 has the same config, but it's clocked lower and has a correspondingly lower TDP.

Whereas the 7965WX has 24 cores from 4 CCDs, so the 7965WX is presumably made of CCDs where 2 of the 8 cores were defective, i.e. it's a 7975WX made of "defective" CCDs. But so is the EPYC 9254. Or they could have used the same four "defective" CCDs to make a pair of the 12-core Ryzen 9 7900, or four of the Ryzen 5 7600.

The EPYC "F" processors are apparently made entirely of "defective" CCDs, presumably because it gives them more L3 cache per core and helps with heat dissipation by spreading the heat load across more CCDs for the same number of cores.
