Zen 3 is a microarchitecture developed by AMD as a successor to Zen 2. It was publicly released on October 8, 2020. Mainstream Desktop processors hit shelves on November 5, 2020.

History

Zen 3 was formally disclosed in a roadmap by Lisa Su, AMD's CEO, during AMD's Tech Day in February of 2017. Zen 3 will be the 3rd iteration of the Zen microarchitecture. On Investor's Day in May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 3 is set to utilize 7nm+ process.

Products

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.

Product Line	Cores/Threads	Target
EPYC 7003 "Milan"	Up to 64/128	High-end server multiprocessors
Trento	?/?	High-performance computing
Genesis Peak	?/?	Workstation & enthusiasts market processors
Ryzen 5000 "Vermeer"	Up to 16/32	Mainstream to high-end desktops & enthusiasts market processors
Ryzen 5000 APU "Cezanne"	Up to 8/16	Mainstream desktop & mobile processors with GPU

Process technology

Zen 3 will be fabricated on TSMC's 7nm+ process, the same process used in Zen 2 Refresh processors.

Architecture

There is very limited information available about the architectural improvements of Zen 3.

Key changes from Zen 2

CCD
- Unified 8-core CCX (from 2x 4-Core CCX per CCD)
- 32 MiB L3$ available equally to all cores in CCD.
  - Decreased L3 latency (~46 cycles, up from ~40 cycles)
Core
- Higher IPC (AMD self-reported +19% IPC)
- Front-end
- Increased branch prediction bandwidth
  - "zero-bubble" branch prediction
  - L1 BTB doubled from 512 to 1024 entries
- Improved prefetching
- Improved µop cache
Back-end
- Floating point unit:
  - FMA latency reduced by 1 cycle from 5 to 4.
  - Fifth and sixth dedicated execution ports added for floating point store and FP-to-int transfer, no longer sharing 2nd FADD port.
  - Unified scheduler split into 1 scheduler per FMA/FADD/transfer port set.
  - 256b VAES and VPCLMULDQ support for doubled AES and AES-GCM cryptographic throughput.
  - Hardware implementation of BMI2 PDEP/PEXT bit scatter/gather operations, compared to prior microcode emulation.
- Integer unit:
  - Integer physical register file increased from 180 to 192 entries
  - Issue increased from 7 (existing 4 ALU and 3 AGU) to 10 with 1 new dedicated branch execution port and 2 separated store data pathways.
  - Schedulers shared between pairs of ALU + AGU/branch ports instead of dedicated for each.
  - Instruction redundancy increased between ports for reduced bottlenecking on a wider variety of instruction streams.
  - 8/16/32/64 bit signed integer division/modulo latency improved from 17/22/30/46 cycles to 10/12/14/20. (Unsigned operations are ~1 cycle faster for some of both old/new cases.) Throughput improves proportionately.
- Load/store:
  - Load throughput increased from 2 to 3, if not 256b.
  - Store throughput increased from 1 to 2, if not 256b.
  - Store queue increase from 48 to 64 slots.
  - Page table walkers tripled from 2 to 6 for TLB miss handling.
