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.
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.

Process Technology
- See also: 12 nm process
Zen is manufactured on Global Foundries' 12 nm process Leading-Performance (12LP), an enhanced version of their 14nm process. The enhanced process is set to provide as much as 15% higher density and 10% higher performance. 12LP brings around a 10% frequency bump for the Ryzen lineup at the same power envelopes.
Compatibility
Linux added initial support for Zen starting with Linux Kernel 4.10. Microsoft will only support Windows 10 for Zen.
Vendor | OS | Version | Notes |

Windows 10 | Support | ||
Linux | Linux | Kernel 4.10 | Initial Support |
Compiler support
Zen+ is largely the same architecture as Zen and thus uses the same compiler switches.

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.

Pipeline
Zen+ pipeline is identical to Zen's.
Memory Subsystem
When AMD presented their paper at ISSCC 2018, WikiChip was able to confirm with AMD's SoC architect that Zen's L2 latency was always designed to be 12 cycles. In fact all Zen-based microprocessors (including EPYC, Ryzen Threadripper, and Zen-based APUs) have an L2 latency of 12 cycles for all patterns. Only mainstream Zen-based Ryzen processors (i.e., Summit Ridge) have a latency of 17 cycles. The problem has been sorted out with Zen+.
Sockets/Platform
All Zen+-based mainstream consumer microprocessors utilizes AMD's Socket AM4, a unified socket infrastructure. All those processors are a complete system on a chip integrating the northbridge (memory controller) and the southbridge including 16 PCIe lanes for the GPU, 4 PCIe lanes for the NVMe/SATA controllers as well as USB 3.0. The chipset, however, extends the processor with a number of additional connections beyond that offered by the SoC.
