| Succession | |
Zen 2 (formerly Zen+) 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. Zen 2 (then Zen+) was initially mentioned by AMD's senior fellow and lead architect of Zen, Michael Clark, during Hot Chips 28 in 2016 as part of AMD's continuing commitment in the high-performance computing market. 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 3 is set to utilize GlobalFoundries' 7 nm process.
