First off, here are the processors that have been released. There are nine in total, ranging from 8-core/16-thread parts all the way up to 32-core/64-thread parts.

AMD EPYC

The EPYC 7000-series processors all have the following features:

  • Up to 32 high-performance “Zen” cores
  • Eight DDR4 channels per CPU
  • Up to 2TB RAM per CPU
  • 128 PCIe lanes
  • Dedicated security subsystem
  • Integrated chipset
  • Socket-compatible with next-gen EPYC processors
AMD EPYC

AMD uses Infinity Fabric for both die-to-die and socket-to-socket interconnect (in a dual-socket arrangement, each processor dedicates 64 PCIe lanes to Infinity Fabric).

Infinity Fabric allows for near-perfect performance scaling when going from single-socket to dual-socket servers.

AMD has designed EPYC to allow for “no compromise” single-socket systems with no artificial limitations placed on performance.
