The 32-Core AMD Naples CPU Tech Report

Just 3 months ago, we revealed to you the first AMD Naples + Radeon Instinct reference design. Yet, details were scarce. Now that AMD has finally launched their Ryzen 7 desktop processors, they are finally ready to reveal details of the AMD Naples CPU.



AMD Naples Revealed!

Like Ryzen, the AMD Naples CPU is based on their brand-new Zen microarchitecture. Designed for servers, the Naples CPU offers up to 32 processor cores, an integrated high-speed DDR4 memory controller and a new high-speed coherent interconnect.

These four slides summarises the Naples CPU’s key features :

  • 32 AMD Zen cores., each capable of handling 2 simultaneous threads.
  • Integrated DDR4 memory controller with 8 memory channels, each supporting two DIMMs. That’s a total of 16 DIMMs per processor socket, allowing for up to 2 TB of memory. A 2-socket server will support up to 32 DIMMs, with a total memory capacity of 4 TB.
  • The Naples CPU is fully integrated with high-speed I/O including 128 PCIe 3.0 lanes.
  • Because the Naples is a complete SoC, there is no need for a separate chipset, reducing cost and power consumption.

In a 2-socket system, two Naples CPUs will communicate with each other via the AMD Infinity Fabric coherent interconnect. Even though each Naples CPU technically supports 128 PCIe 3.0 lanes, it is limited to 64 PCIe 3.0 lanes in a 2-socket design.

A 2-socket Naples server would offer 64 processor cores that can handle 128 simultaneous cores, and up to 4 TB of DDR4 memory (32 x 128 GB DIMMs). Just how fast is such a server? Let’s find out…
