Rome is codename for AMD's high-performance server microprocessors based on the Zen 2 microarchitecture serving as a successor to Naples.

Rome-based microprocessors are branded as second-generation, 7002-series, EPYC processors.

AMD datacenter roadmap

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
