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.
Contents
History
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.

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 |
|---|---|---|
| Pinnacle Ridge | Up to 8/16 | Mainstream to high-end desktops & enthusiasts market processors |
| Picasso | 4/8 | Mainstream desktop & mobile processors with GPU |
Release Dates
AMD intends on launching 2nd generation Ryzen in April of 2018. 2nd Generation Ryzen Threadripper and Ryzen PRO processors will launch in the second half of 2018.
Architecture
Serving as a light refresh over Zen, those processors have around ten percent higher base frequency for the same power envelope.
Key changes from Zen
- ~10% higher clock frequency
- 12 nm process (from 14 nm)
- Precision Boost 2 (from Precision Boost)
- Mainstream chipsets (See § Sockets/Platform)
- X370 → X470
- Lower Power
- Bug fixes
- OEM related issues resolved (unspecified)
- X370 → X470
