It is known that Zen 2 is on the horizon, with the upcoming announcement of a new generation of processors at Computex during the month. AMD did not keep this secret. In fact, AMD recently recalled that Zen 2 products will be released in the third quarter of this year, and include consumer desktop processors (Ryzen 3000 series) and servers (EPYC). Regarding this last point, a new leak gives us an overview of the specifications and performance of certain offers proposed by AMD.
To quickly recap, Zen 2 is the third generation of Zen microarchitecture of AMD. This is the first in the Zen series to use a 7 nanometer manufacturing process. Parts of the current generation Zen + are built on a manufacturing process of 12 nm, while the first generation Zen a process node of 14 nm. The move to 7nm should introduce better IPC performance (clock instructions), more cores, faster clocks, and improved power efficiency.
On the server side, the future EPYC lineup based on Zen 2 (codename Rome) will range from 64 physical cores to 128 strings of calculating muscle. AMD criticized the performance of an EPYC 64 core / 128 thread processor earlier this year, showing that it outperformed two Intel Xeon Platinum 8180M processors, which are both 28-core / 56-threaded processors. Obviously, AMD uses an advantage in terms of the number of threads and cores, but AMD thinks that this kind of first-rate performance can be achieved from a single processor configuration.
Fast forward to now and some EPYC Rome processors have appeared in the SiSoft SANDRA database. One is a 32-core / 64-threaded chip and the other is a 64-core / 128-threaded processor, both based on Zen 2.

Starting with the 64-core / 128-threaded monster, the database entry (which has since been deleted, but not before). WCCFTech could hang a screenshot) indicated that it was a technical sample called ZX1406E2VJUG5_22 / 14_N. From there, it can be extrapolated that it has a basic clock at 1.4 GHz and a clock Turbo at 2.2 GHz. Of course, being an ES chip, these clocks are likely to be lower than they will be on the final silicon.
When this entry was available, it ranked third in terms of arithmetic scores in the database. Factor of higher shipping clocks, and this could be a compelling product in the server market.

The 32-core / 64-threaded EPYC processor was also an engineering sample called ZS1711E3VIVG5_24 / 17_N. Based on this information, it was running with a 1.7 GHz base clock and a 2.4 GHz boost clock, which is a bit faster than the 64-core / 128-threaded ES chip above.
What will be interesting is the way all of AMD's product lines integrate with Zen 2 material, which adds more hearts and threads to the equation. For example, AMD's second generation Threadripper processors already fit 32 cores and 64 threads (Threadripper 2990WX). There are some key differences between Threadripper and EPYC, but it's interesting to see the overlap.
The same goes for the future processors of the Ryzen 3000 series, which, according to rumors, would be offered in 16 cores and 32 threads at most. It encroaches on the territory of Threadripper. Surprisingly, Threadripper oddly lacks the latest AMD roadmap made available to the public.
