Well we now that this CPU exist, or it is first AMD CPU product on TSMC 7nm.
Ok this is Trailer for "old Epyc CPU-s",
"but 64 Cores/ 128 Threads this is to much performanse and options etc".
I have no doubts that a 64-core EPYC will exist sooner or later, but rather if the alleged leak is even remotely accurate in terms of the used hardware (or at all).
The existing SP3 boards (which must be compatible with the upcoming Rome SKUs as well), have been designed for 200W max. sustained power draw (180W TDP with cTDP upconfig).
Even if the alleged 64C SKU had 50% higher power rating (i.e. 300W) and provided had >= 10% higher IPC in Cinebench R15 specifically, it still would need to have > 83% higher power efficiency than the parts made on 12nm LP.
Not very likely, as the CPU should be running closer to 4GHz to produce that kind of a score.
If there is any truth in the alleged leak, it is most certainly a 2P (i.e. 2x 64C/128T) system running at low speeds.
Being real would also mean that it is a rather early prototype part, which tend to run at even low(er) speeds than the generally low clocked high core count server parts already do.
In case you think it is real deal (which I personally don't), ask yourself which is more likely: An early prototype 64C/128T CPU running at < 4GHz or two early prototype 64C/128T CPUs running at < 2GHz in a 2P system?
While I have no doubts regarding the superiority of the 7nm process from TSMC compared to GF 12/14nm processes, I cannot see the supplied information adding up even remotely considering the realistic characteristics of a server CPU and the existing infrastructure especially.
It is also becoming a habit that fake AMD news gets "leaked" when Intel is close to releasing something new. When 8700K was to be released we were seeing "news" about Ryzen 5 series CPUs shipping with all 8 cores enabled. Now that Coffee Lake Refresh is about to be released, we've already seen "Ryzen 7 2800X with 10 cores" and now this.
