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[edit]

amd zen future roadmap.jpg

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.

Process technology[edit]

Zen 3 is fabricated on TSMC's 7nm+ process for the Core Compute Die (CCD), the same process used in Zen 2 Refresh processors, as well as GlobalFoundries 12nm process for the Input/Output Die (IOD).

Note: Only the APU series of microprocessors retains the monolithic design, so they are fabricated solely on TSMC's 7nm+ process.

Compiler support[edit]

Compiler Arch-Specific Arch-Favorable
GCC -march=znver3 -mtune=znver3
LLVM -march=znver3 -mtune=znver3
  • Note: Initial support in GCC 10.3 and LLVM 12.0.

        • 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.
