AMD Zen 3-based EPYC Milan said to be 20 percent faster than Rome

German tech reporter Andreas Schilling from Hardwareluxx got his hands on OEM documentation that provides details about AMD's EPYC "Milan" processors, which use Zen 3-based cores. The documentation indicates these upcoming server processors offer up to 20 percent higher performance than the current-generation "Rome" processors. About 15 percent is the result of an uplift in IPC performance and another 5 percent has been gained via higher clockspeeds.

It's unknown how this will translate for Vermeer, the Zen 3-based desktop processors that will launch later this year.
The report claims that AMD's 64-core designs will feature a lower-clock all-core operating mode, and a 32-core alternate for less threaded workloads where extra frequency is added to the working cores. Apparently, AMD's approach for the Zen 3 architecture does away with L3 subdivisions according to CCXs; now, a full 32 MB of L3 cache is available for each 8-core Core Compute Die (CCD). AMD has apparently achieved new levels of frequency optimization under Zen 3, with higher upward frequency limits than before.
