AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm). AMD Zen 2 Family 17h – second generation Zen architecture based on 7 nm process, first architecture designed around chiplet technology. [3] AMD Zen 3 Family 19h – third generation Zen architecture in the optimised 7 nm process with major core redesigns. [4]
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.
16 KB 4-way of L1d (way-predicted) per core and 2-way 64 KB of L1i per module, one way for each of the two cores [15] [16] [17] 2 MB of L2 cache per module (shared between the two integer cores) Write Coalescing Cache [18] is a special cache that is part of L2 cache in Bulldozer microarchitecture.

Zen+ is the name for a computer processor microarchitecture by AMD.It is the successor to the first gen Zen microarchitecture, [3] and was first released in April 2018, [4] powering the second generation of Ryzen processors, known as Ryzen 2000 for mainstream desktop systems, Threadripper 2000 for high-end desktop setups and Ryzen 3000G (instead of 2000G) for accelerated processing units (APUs).
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.
