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.
