Rome codename for AMD's high-performance enterprise-level server multiprocessors based on the Zen 2 microarchitecture serving as a successor to Naples. Rome-based chips are fabricated on TSMC 7 nm process with some components made on GlobalFoundries 14 nm process.

AMD datacenter roadmap

Overview

AMD Rome system on chips are a series of high-performance multiprocessors designed by AMD based on their Zen 2 microarchitecture. Rome SoCs support both single and 2-way multiprocessing with up to a maximum of 64 cores (and 128 threads) per processor for a total of up to 128 cores (and 256 threads) for a 2-way MP system. Those SoCs sports 128 PCIe lanes each, however, half of them are lost when in 2-way MP (leaving the system with the same overall lanes count as a single socket solution). Communication between the two chips is done via AMD's Infinity Fabric protocol over the 64 reserved lanes. Rome is backwards platform/socket compatible with Naples and forward-compatible with Milan.

Common Features

All Rome processors have the following:

• 128 PCIe lanes (in both single-way and dual-way multiprocessing)
  • PCIe Gen 4
• Octa-channel Memory
  • Up to DDR4-2666 ECC
  • Up to 4 TiB (8 TiB in 2MP)
• Up to 64 cores / 128 threads
• Everything up to AVX2 (i.e., SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2), and SHA
