The 24-core Threadripper doesn't have full memory bandwidth from all dies. It's build from 4 dies with 6 enabled cores each, and like for the 32-core Threadripper, only 2 of those dies have memory channels enabled.
You're right about the 16-core Threadripper being built from 2 dies, though the EPYC should still be able to do better at I/O, since I believe it's built from 4 dies, all of which have active memory controllers. So you basically get 2x the memory bandwidth.
