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 ...
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]
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 ...
Coming to AMD’s upcoming Ryzen 8000G series chips, which hit the market Jan. 31, the NPU is designed to handle AI-based tasks on your desktop computer without having to send data to the cloud.
Sinkclose is a security vulnerability in certain AMD microprocessors dating back to 2006 that was made public by IOActive security researchers on August 9, 2024. [1] IOActive researchers Enrique Nissim and Krzysztof Okupski presented their findings at the 2024 DEF CON security conference in Las Vegas [2] in a talk titled "AMD Sinkclose: Universal Ring-2 Privilege Escalation".
In January 2018 AMD has announced their new lineup plans, with Ryzen 2. [185] AMD launched CPUs with the 12nm Zen+ [186] microarchitecture in April 2018, following up with the 7nm Zen 2 microarchitecture in June 2019, including an update to the Epyc line with new processors using the Zen 2 microarchitecture in August 2019, and Zen 3 slated for ...
Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen (including Zen+, Zen 2 and Zen 3) and Excavator microarchitectures. [ 1 ] [ 2 ] AM4 was launched in September 2016 and was designed to replace the sockets AM3+ , FM2+ and FS1b as a single platform.
Zen 2 also powers a line of mobile and desktop APUs marketed as Ryzen 4000, as well as fourth generation Xbox consoles and the PlayStation 5. The Zen 2 core microarchitecture is also used in the Mendocino APU, a 6 nm system on a chip aimed at mainstream mobile and other energy efficient low power computing products. [29]
