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 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).
