Game-Changing AMD EPYC

Today, a large percentage of datacenter applications are limited by memory constraints. When resources are delivered in the wrong ratios, performance and cost effectiveness suffer.

The AMD EPYC SoC brings performance optimization to a higher level, delivering the highest core count and memory capacity; and the greatest memory bandwidth, and I/O density in the industry.

Real-world performance depends not just on raw capabilities, but on the ratio of resources to balance performance and minimize bottlenecks. The AMD EPYC SoC has the memory capacity and bandwidth to satisfy the high demand of the processor cores for data. It has I/O bandwidth that matches the capability of the CPU cores to move data to and from the network, spinning disks, NVMe storage, and graphics acceleration devices.

Compare

According to AMD, the AMD EPYC processor:

  1. Supports up to 21.3 GBs per channel with DDR4-2666 x 8 channels (total 170.7 GBs), versus the Xeon E5-2699A v4 processor at 19.2 GBs with max DDR4-2400 x 4 channels (total 76.8 GBs). NAP-03
  2. Offers up to 128 PCI Express high speed I/O lanes per socket, versus the Xeon E5-2699A v4 processor at 40 lanes per socket. NAP-05
  3. Includes up to 32 CPU cores versus the Xeon E5-2699A v4 processor with 22 CPU cores. NAP-02

Features/Benefits (per CPU)

  • Up to 32 high-performance cores (64 threads): Boosts performance and compute density
  • Up to 2TB of DDR4 memory capacity (across 8 channels): Accelerates memory-intensive application performance
  • 128 Lanes of PCIe® Gen 3: Extends server capabilities without incremental PCI switching
  • Integrated security subsystem: Protects and enables secure multi-tenancy per CPU/SoC

The AMD EPYC SoC bridges current performance gaps with innovations designed from the ground up to efficiently support the needs of existing and future datacenters.

  • The highest core count in an x86-architecture server processor, largest memory capacity, most memory bandwidth, and greatest I/O density are brought together with the right ratios to reach new levels of performance.
  • Match core count with application needs without compromising processor features.
  • AMD created the first dedicated security processor embedded in an x86-architecture server SoC. The processor manages secure boot, memory encryption, and secure virtualization on the SoC itself. Encryption keys never have to leave the processor.
