Zen is a family of computer processor microarchitectures from AMD, first launched in February 2017 with the first generation of its Ryzen CPUs. It is used in Ryzen (desktop and mobile), Ryzen Threadripper (workstation and high end desktop), and Epyc (server).
The AMD Optimizing C/C++ Compiler (AOCC) is an optimizing C/C++ and Fortran compiler suite from AMD targeting 32-bit and 64-bit Linux platforms. [1] [2] It is a proprietary fork of LLVM + Clang with various additional patches to improve performance for AMD's Zen microarchitecture in Epyc, and Ryzen microprocessors.
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.

Zen 5 is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022, [3] launched for mobile in July 2024 and for desktop in August 2024. [4] It is the successor to Zen 4 and is currently fabricated on TSMC's N4X process. [5] Zen 5 is also planned to be fabricated on the N3E process in the future. [6]
Zen 6 is the name for an upcoming CPU microarchitecture from AMD, shown on their roadmap in July 2024. [1] [2] It is the successor to Zen 5 and is believed to use TSMC's 3 nm and 2 nm processes. Desktop processors will be codenamed "Medusa" under the Ryzen 10000 name, [3] while Epyc server processors will be codenamed "Venice". [4]
