Epyc is 4 ryzen 7's. The threadripper (at least the ones shipping today) are two Ryzen 7s.
The memory bandwidth does increase proportionally (it's 2x ryzen for threadripper and 4x ryzen for eypc).
Individual cores do tend to be lower on the threadripper and epyc because of power/heat limitations, so they tend to be lower clocked and tend to have less cache per core.
- JoshuaJB 8y agoAccording to the linked article, Threadripper 2 uses the equivalent of 4 Ryzen 7s, however they disable the memory busses on two of them which yields only a 2x increase in memory bandwidth. You're correct that Threadripper tends to clock slightly lower, but the cache is on-die so it shouldn't be any different per-core than in a typical Ryzen.
