It is commonly known that Zen 2 is on the horizon with a new generation of processors that are likely to be announced at Computex later this month. AMD has not kept this a secret. In fact, AMD recently reiterated that the Zen 2 products should be shipped in the third quarter of this year, including both the Consumer Station (Ryzen 3000 series) and server (EPYC) processors. For the latter, a fresh leak gives us a sneak peek at the specifications and performance of some of the offers made by AMD.
To quickly restore Zen 2 is the third generation of AMD's Zen micro-architecture. It is the first of the Zen series to utilize a 7-nanometer manufacturing process. Current generation Zen + parts are built on a 1
2nm manufacturing process, while the first Zen used a 14nm process node. Moving to 7nm is expected to introduce better IPC (instructions per clock) performance, ore kernels, faster bells and improved efficiency.
On the server side, the upcoming Zen 2-based EPYC lineup (codenamed Rome) will scale to 64 physical cores and 128 threads of computer muscle. AMD teased the performance of a 64-core / 128-wire EPYC processor earlier this year, showing that it exceeded two Intel Xeon Platinum 8180M processors, both of which are 28-core / 56-threaded CPUs. in the C-Ray benchmark. It is clear that AMD works with an advantage in core and wire counts, but the pitch of AMD is that this type of top quality can be obtained from a single processor setup.
Fast forward to now and there are a couple of EPYC Rome processors that have appeared in SiSoft SANDRA's database. One is a 32-core / 64-wire chip and the other is a 64-core / 128-wire CPU, both based on Zen 2.

Beginning with the 64-core / 128-threaded monster, the database record (which has since been removed but not before WCCFTech could snag a screenshot) indicated that was a technical sample marked ZX1406E2VJUG5_22 / 14_N. Thus, we can extrapolate that it has a 1.4 GHz base clock and 2.2 GHz Turbo clock. Of course, being an ES chip, these watches are very likely to be lower than what they will be on the final silicon.
When this record was available, it was placed third in relation to the database's arithmetic score. Factor in higher freight clocks, and this could be a convincing product on the server market.

As for 32-core / 64-wire EPYC processor, it also appeared as an engineering test, labeled ZS1711E3VIVG5_24 / 17_N. Based on this information, it ran with a 1.7 GHz base clock and 2.4 GHz boost clock, which is slightly faster than the 64-core / 128-threaded ES chip above.
What will be interesting is how all AMD's product lines interfere with Zen 2 things that add more cores and threads to the equation. For example, AMD's second generation Threadripper processors are already on a scale to 32 cores and 64 threads (Threadripper 2990WX). There are some important differences between Threadripper and EPYC, but it is interesting to see the overlap.
The same goes for future Ryzen 3000 series processors rumored to be offered in up to 16 cores and 32 threads. It goes over Threadripper territory. Interestingly, Threadripper lacks the curiosity of AMD's latest roadmap that was made available to the public.
