AMD Launches 64-core / 128 Threaded 2nd Gen AMD EPYC Processors
An exciting day for AMD as they introduced its second generation of Epyc server processors. Epyc 7002 processors (Rome) get a massive 64 cores for its flagship models. That's twice what it was a year ago. These puppies can do 3.4 GHz as long as a maximum of eight cores and have an all-core turbo of 3.2 GHz.
Epyc Gen 2 is based on the all-new Zen 2 (7nm) used in Ryzen 3000 processors for desktops and thus bring a healthy IPC increase as well. Of course, that also means Epyc brings support for PCI-express 4.0 and has 128 lanes available. 256G / s of PCIe bandwidth is therefore available in both directions. Each Epyc CPU has eight DDR4-3200 memory channels, in which a maximum of 4 TB of working memory can be installed per socket. The CPUs are based in the chiplet design, meaning AMD has a separated IO die next to the 8-core dies. AMD also emphasizes that it has a safer architecture compared to the competition.
Epyc 7002 processors use the same SP3 socket as the first generation of Epyc CPUs. After a bios update, the new models can be used in motherboards and servers. A total of 18 processors will become available from 8, 12, 16, 24, 32, 48 and 64 cores. The top model is the Epyc 7742, a 64-core CPU with a 225 watt TDP and 256 MB L3 cache.

Exactly what I was thinking!!! Bring on the new TR platform, I can't freaking wait for 64/128 logical cores!!!!

The server platform is where the most innovative ideas are brought and breed. After a while, some things end up on the desktop platform.
AMD just accelerate this process, and gone are the days when only a few selected mortals were able to purchase Xeons with more than 4C/4T.
It is a generalization, for sure there are details than we can debate on, no point in starting an argument.
Amdahl's law is today's status quo.

Anandtech did a preliminary bunch of tests and seemed quite excited about it both on bang and then doubly on bang per buck. Hopefully it will make inroads into the enterprise sector and get some good profits for AMD.
