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.

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
  • +19% IPC
  • Improved µop cache
