Succession
Zen+ Zen 3

Zen 2 is AMD's successor to Zen+, a 7 nm process microarchitecture for mainstream mobile, desktops, workstations, and servers. Zen 2 will eventually be replaced by Zen 3.

For performance desktop and mobile computing, Zen is branded as Ryzen 3, Ryzen 5, Ryzen 7 and Ryzen Threadripper processors. For servers, Zen is branded as EPYC.

History

Zen 2

Zen 2 is set to succeed Zen in 2019. 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 2 is set to utilize 7 nm process. Initial details of Zen 2 and Rome were unveiled during AMD's Next Horizon event on November 6 2018.

Zen 2 on the roadmap

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
Rome	Up to 64/128	High-end server multiprocessors

Process technology

Zen 2 is fabricated on TSMC's 7 nm process. Some components of the chips (e.g., I/O die) are fabricated on GlobalFoundries 14 nm process.

Compiler support

Compiler	Arch-Specific	Arch-Favorable
GCC	-march=znver2	-mtune=znver2
LLVM	-march=znver2	-mtune=znver2

• Note: Initial support in GCC 9 and LLVM 9.

Architecture

Zen 2 inherits most of the design from Zen+ but improves the instruction stream bandwidth and floating-point throughput performance.

Key changes from Zen+

• 7 nm process (from 12 nm)
  • I/O die still utilizes 14 nm

    • Improved µOP cache tags
    • Improved µOP cache
      • Larger µOP cache (?? entries, up from 2048)
    • Increased dispatch bandwidth
  • Back-end
    • Increased retire bandwidth (??-wide, up from 8-wide)
    • FPU
      • 2x wider datapath (256-bit, up from 128-bit)
      • 2x wider EUs (256-bit FMAs, up from 128-bit FMAs)
      • 2x wider LSU (2x256-bit L/S, up from 128-bit)
• Security
  • In-silicon Spectre enhancements
  • Increase number of keys/VMs supported
• I/O
  • PCIe 4.0 (from 3.0)
  • Infinity Fabric 2
    • 2.3x transfer rate per link (25 GT/s, up from ~10.6 GT/s)

This list is incomplete; you can help by expanding it.

New instructions

Zen 2 introduced a number of new x86 instructions:

• CLWB - Force cache line write-back without flush
• RDPID - Read Processor ID

Core

Zen 2 largely builds on Zen. Most of the fine details have not been revealed by AMD yet.

Front End

In order to feed the backend, which has been widened to support 256-bit operation, the front-end throughput was improved. AMD reported that the branch prediction unit has been reworked. This includes improvements to the prefetcher and various undisclosed optimizations to the instruction cache. The µOP cache was also tweaked including changes to the µOP cache tags and the µOP cache itself which has been enlarged to improve the instruction stream throughput.

Execution Engine

AMD stated that both the dispatch bandwidth and the retire bandwidth has been increased.

Floating Point

The floating-point unit underwent major modifications in Zen 2. In Zen, AVX2 256 bit single and double precision vector floating-point data types were supported through the use of two 128 bit micro-ops per instruction. Likewise, the floating-point load and store operations were 128 bits wide. In Zen 2, the datapath and the execution units were widened to 256 bits, doubling the vector throughput of the core.

With two 256-bit FMAs, Zen 2 is capable of 16 FLOPs/cycle.

Rome

Rome is codename for AMD's server chip based on the Zen 2 core. Like prior generation (Naples), Rome utilizes a chiplet multi-chip package design. Each chip comprises of nine dies - one centralized I/O die and eight compute dies. The compute dies are fabricated on TSMC's 7 nm process in order to take advantage of the lower power and higher density. On the other hand, the I/O makes use of GlobalFoundries mature 14 nm process.

The centralized I/O die incorporates eight Infinity Fabric links, 128 PCIe Gen 4 lanes, and eight DDR4 memory channels. The full capabilities of the I/O have not been disclosed yet. Attached to the I/O die are eight compute dies - each with eight Zen 2 core - for a total of 64 cores and 128 threads per chip.
