AMD EPYC Data Center CPU Launched

AMD has launched its new series of high-performance data center processors, AMD EPYC 7000 series. AMD is announcing the launch with support from a wide array of customers and partners including HPE, Dell, Asus, Gigabyte, Inventec, Lenovo, Sugon, Supermicro, Tyan, Mellanox, Samsung Electronics, Xilinx, and Wistron among others. The EPYC series is designed with up to 32 “Zen” cores and an unparalleled feature set, delivers greater performance than the competition across a full range of integer, floating point, memory bandwidth, and I/O benchmarks and workloads.

All the new EPYC processors combine security features, enterprise class reliability, and support a full feature-set. AMD goes on to claim that at "every targeted price point for two-socket processors, EPYC outperforms the competition, with up to 70% more performance in the eight hundred dollar price band and up to 47% more performance at the high-end of the market of four thousand dollars or more." With a specific dig at Intel, AMD states that its EPYC 7601 one-socket system shifts expectations for single socket server performance, helping lower total-cost-of-ownership (TCO), providing up to 20% CapEx savings compared to the Intel Xeon E5-2660 v4-based two-socket system.

Features include:

  • A highly scalable System on Chip (SoC) design ranging from 8-core to 32-core, supporting two high-performance threads per core
  • Industry-leading memory bandwidth across the line-up, with 8 channels of memory on every EPYC device. In a two-socket server, support for up to 32 DIMMS of DDR4 on 16 memory channels, delivering up to 4 terabytes of total memory capacity
  • Unprecedented support for integrated, high-speed I/O with 128 lanes of PCIe 3 on every product
  • A highly-optimized cache structure for high-performance, energy efficient compute
  • AMD Infinity Fabric coherent interconnect linking EPYC CPUs in a two-socket system
  • Dedicated security hardware

High performance in a processor is always going to grab attention. AMD has stating that the new EPYC series hits record-setting performance and then released some of the record that the new processor set, including:

  • Two-Socket Server
    • AMD EPYC 7601-based system scored 2360 on SPECint®_rate2006, higher than any other two-socket system score
  • One-Socket Server
    • AMD EPYC 7601-based system scored 1200 on SPECint®_rate2006, higher than any other mainstream one-socket x86-based system score
    • AMD EPYC 7601-based system scored 943 on SPECfp®_rate2006, higher than any other one-socket system score

As stated above, several partners and customers greeted this launch with open arms due to the potential the new series can drive. Dell EMC specifically announced that it would be adding the new EPYC 7000 Series to its popular 14G PowerEdge Series of servers. The EPYC series can complement and augment the PowerEdge servers with its ability to support up to 24 NVMe devices on a single processor and further strengthening the security of the servers with the inclusion of Boot-Safe and Run-Safe technologies.
