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

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.

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
Microsoft Windows Windows 7 No Support
Windows 8 No Support

Compiler support

With the release of Ryzen, AMD introduced their own compiler: AMD Optimizing C/C++ Compiler (AOCC). AOCC is an LLVM port especially modified to generate optimized x86 code for the Zen microarchitecture.

Compiler Arch-Specific Arch-Favorable
AOCC ‐march=znver1 -mtune=znver1
GCC -march=znver1 -mtune=znver1
LLVM -march=znver1 -mtune=znver1
Visual Studio /arch:AVX2  ?

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.

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)
  • XFR 2 (from XFR 1)
  • Memory
    • Improved cache prefetch
    • Higher DDR4 transfer rate (2933 MT/s from 2666 MT/s)
  • Mainstream chipsets (See § Sockets/Platform)
    • X370 → X470
      • Lower Power
      • Bug fixes
      • OEM related issues resolved (unspecified)

Memory Hierarchy

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.
