A family of CPUs for the server and embedded systems market from AMD. Introduced in 2017, EPYC chips have from 32 to 64 cores, considerably more than their desktop counterparts. Expected in 2022, the 4th-generation of the EPYC family will have 96 cores.
EPYC chips have built-in security features for virtual machine processing in datacenters. Using randomly generated AES hardware keys, AMD's Secure Encrypted Virtualization (SEV) encrypts each VM's memory. SEV also encrypts the registers. See
