In a bold effort on penetrating Intel's x86 server broad market, AMD has made its next move at this server market glory with Naples, a new AMD 32-core, 64-thread processor based on its powerful Zen architecture.

Overall, AMD's new Naples CPU targets the high-performance server market and confirms to the industry that the chip maker wants to be a significant data centre player when it comes to microarchitecture.

The new Naples CPU features:

  • Scalable, 32-core System on Chip design, with two threads per core
  • Up to 16 DDR4 DIMMS on 8 memory channels, up to 2 TB of memory capacity
  • Support for up to 32 DIMMs of DDR4 on 16 memory channels, delivering up to 4 TB of total memory capacity in a 2-socket server
  • Complete SoC with fully integrated I/O supporting 128 lanes of PCIe 3
  • Cache structure for high-performance, energy efficient computing
  • Infinity Fabric coherent interconnect for Naples CPUs in a 2-socket system
  • Dedicated security hardware
  • Naples will be able to directly attach multiple Radeon Instinct GPUs to accelerate things like VDI and image-processing workloads.

    During a preview webcast, AMD ran an analysis processing demonstration to show Naples outperforming Intel CPUs with 44 cores.

    When Naples ran with 64 cores, it outperformed the Intel system by about 2 1/2 times.

    AMD's Forrest Norrod, general manager for the Enterprise, Embedded and Semi-Custom Business Group, says Naples "exceeds today's top competitive offerings on critical parameters, with up to 45 percent more cores, 60 percent more input/output capacity, and 122 percent more memory bandwidth."

    He says that Intel's Xeon E5-2699A v4 processor has up to 22 CPU cores. The E5-2699A v4 processor has 40 PCI Express lanes per socket while Naples has 64.

    Additionally, Naples supports up to 21.3 GBps per channel with DDR4-2667 x 8 channels (total 170.7 GBps), versus the E5-2699A v4 processor's implied 140 GBps.

    Norrod also stated that two-socket servers built with Naples will have the flexibility, performance and security to support various server workloads that once required 4-socket or larger server configurations.

    Enterprise customers can now support even more virtual machines per server in virtualized and cloud computing environments. In addition, they can process even more data in parallel, and execute more high-performance computing workloads that require massive parallelism, he asserted.
