Revision as of 21:31, 6 August 2019

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.

Process technology

Zen 2 comprises multiple different components:

The Core Chiplet Die (CCD) is fabricated on TSMC 7 nm HPC process
The client I/O Die (cIOD) is fabricated on GlobalFoundries 12 nm process
The server I/O Die (sIOD) is 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.

This article is a work in progress!

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

New instructions

Zen 2 introduced a number of new x86 instructions:

CLWB - Write back modified cache line and may retain line in cache hierarchy
WBNOINVD - Write back and do not flush internal caches, initiate same of external caches
RDPID - Read Processor ID

Core

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

This article is a work in progress!

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.
