Succession

Zen+ (Zen Plus) is a planned microarchitecture being developed by AMD as a successor to Zen. Zen+ is expected to be succeeded by Zen 2.

Zen+ based processors are sold under the brand Ryzen 2nd Generation.

History[edit]

amd zen+ roadmap.png

Zen+ is set to succeed Zen in April of 2018. Zen+ will feature the same core as Zen but will take advantage of the new GlobalFoundries' 12nm process to deliver higher clock speeds and improved power consumption. 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.
