Zen 2 is a planned microarchitecture being developed by AMD as a successor to Zen+. Zen 2 is expected to be succeeded by Zen 3.
History
Zen 2 is set to succeed Zen in the future, sometimes around 2019. In February of 2017 Lisa Su, AMD's CEO announced their future roadmap to include Zen 2 and later Zen 3. On Investor's Day May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 2 is set to utilize GlobalFoundries' 7 nm process.
