Succession

Zen 3 is a planned microarchitecture being developed by AMD as a successor to Zen 2.

History

amd zen future roadmap.jpg

Zen 3 was formally disclosed in a roadmap by Lisa Su, AMD's CEO, during AMD's Tech Day in February of 2017. Zen 3 will be the 3rd iteration of the Zen microarchitecture. On Investor's Day in May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 3 is set to utilize 7nm+ process.

Symbol version future.svg Preliminary Data! Information presented in this article deal with future products, data, features, and specifications that have yet to be finalized, announced, or released. Information may be incomplete and can change by final release.
Core C/T Target
Milan 64/128 High-end server multiprocessors
Genesis Peak  ?/? Workstation & enthusiasts market processors
Vermeer 16/32 Mainstream to high-end desktops & enthusiasts market processors
Cezanne  ?/? Mainstream desktop & mobile processors with GPU

Process technology

Zen 3 will be fabricated on TSMC's 7nm+ process.

Architecture

There is very limited information available about the architectural improvements of Zen 3.

Key changes from Zen 2

  • Unified 8-core CCX with 32 MiB L3$ available to all 8 cores equally
  • Wider and more flexible issue in floating-point and integer engines
  • Increased number of loads and stores, improved prefetching
  • Increased branch prediction bandwidth, "zero-bubble" branch prediction
  • Improved µop cache

This list is incomplete; you can help by expanding it.
