Zen 2 is a computer processor microarchitecture by AMD.It is the successor of AMD's Zen and Zen+ microarchitectures, and is fabricated on the 7 nm MOSFET node from TSMC.The microarchitecture powers the third generation of Ryzen processors, known as Ryzen 3000 for the mainstream desktop chips (codename "Matisse"), Ryzen 4000U/H (codename "Renoir") and Ryzen 5000U (codename "Lucienne") for ...
Then in March 2019, the third iteration of AGESA, named "ComboAM4 PI", was released, starting at version 0.0.7.0, introducing support for Zen 2-based processors. [ 4 ] "ComboAM4v2" supports Zen 3-based processors, while "ComboAM5PI" [ 5 ] supports Zen 4-based processors in socket AM5 motherboards.
Zen 2 introduced the chiplet based architecture, where desktop, workstation, and server CPUs are all produced as multi-chip modules (MCMs); these Zen 2 products utilise the same core chiplets but are attached to different uncore silicon (different IO dies) in a hub and spoke topology.
In July 2023 a critical vulnerability in the Zen 2 AMD microarchitecture called Zenbleed was made public. [59] AMD released a microcode update to fix it. [60] In August 2023 a vulnerability in AMD's Zen 1, Zen 2, Zen 3, and Zen 4 microarchitectures called Inception [61] [62] was revealed and assigned CVE-2023-20569. According to AMD it is not ...
Forward compatibility or upward compatibility is a design characteristic that allows a system to accept input intended for a later version of itself. The concept can be applied to entire systems, electrical interfaces, telecommunication signals, data communication protocols, file formats, and programming languages.
Zen is the first iteration in the Zen family of computer processor microarchitectures from AMD.It was first used with their Ryzen series of CPUs in February 2017. [4] The first Zen-based preview system was demonstrated at E3 2016, and first substantially detailed at an event hosted a block away from the Intel Developer Forum 2016.
