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 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).
AMD chipsets logo. This is an overview of chipsets sold under the AMD brand, manufactured before May 2004 by the company itself, before the adoption of open platform approach as well as chipsets manufactured by ATI Technologies after October 2006 as the completion of the ATI acquisition.
AMD Zen 4 Family 19h – fourth generation Zen architecture, in 5 nm process. [5] Used in Ryzen 7000 consumer processors on the new AM5 platform with DDR5 and PCIe 5.0 support. Adds support for AVX-512 instruction set. AMD Zen 5 Family 1Ah – fifth generation Zen architecture, in 4 nm process. [6] Adds support for full-width AVX-512 pipeline.
The AMD 4700S and 4800S desktop processors are part of a "desktop kit" that comes bundled with a motherboard and GDDR6 RAM. The CPU is soldered, and provides 4 PCIe 2.0 lanes. These are reportedly cut-down variants of the APUs found on the PlayStation 5 and Xbox Series X and S repurposed from defective chip stock. [26] [27] [28]
AMD released the Zen-based high-end Ryzen 7 "Summit Ridge" series CPUs on March 2, 2017, [179] mid-range Ryzen 5 series CPUs on April 11, 2017, and entry level Ryzen 3 series CPUs on July 27, 2017. [180] AMD later released the Epyc line of Zen derived server processors for 1P and 2P systems. [181]
In November 2018, AMD announced Epyc 2 at their Next Horizon event, the second generation of Epyc processors codenamed "Rome" and based on the Zen 2 microarchitecture. [40] The processors feature up to eight 7 nm -based "chiplet" processors with a 14 nm-based IO chip providing 128 PCIe 4.0 lanes in the center interconnected via Infinity Fabric .
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]
