Overview[edit]

AMD Rome system on chips are a series of high-performance multiprocessors designed by AMD based on their Zen 2 microarchitecture. Rome-based logic chips are fabricated on TSMC 7 nm process with the i/o components made on GlobalFoundries 14 nm process. 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 support 128 PCIe lanes each. When in a two-socket configuration, a total of 160 PCIe lanes can be provided at the platform level by both chips. Rome is backward platform/socket (Socket SP3) compatible with Naples and forward-compatible with Milan.

Common Features[edit]

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 DDR4-3200 ECC
    • Up to 4 TiB
      • Up to 16 x 256 GiB @ 1.2 V
      • RDIMM/LRDIMM/3DS/NVDIMM
  • 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
