AMD Ryzen

Ryzen  is a brand of x86-64 microprocessors designed and marketed by Advanced Micro Devices Inc. (AMD) for desktop, mobile and embedded platforms based on the Zen microarchitecture and its successors. It consists of central processing units marketed for mainstream, enthusiast and workstation segments and accelerated processing units (APUs) marketed for mainstream and entry-level segments and embedded applications.

AMD officially announced the first 14nm Ryzen products during its New Horizon summit on December 13, 2016 and introduced them the following February. The second generation of Ryzen CPUs featuring the Zen+ microarchitecture, an incremental improvement built on a 12nm process technology, was released in April 2018. The third generation, based on Zen 2 and featuring more significant design improvements and a further shrink to TSMC's 7nm process, launched on July 7, 2019.

While the majority of Ryzen-branded products are for use with the Socket AM4 platform, in August 2017 AMD added a line of high core count desktop processors aimed at the workstation market with the Ryzen Threadripper branding. Threadripper uses the larger TR4 socket, which supports more memory channels and PCI Express lanes.
