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]
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).
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.
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]
According to the researchers, Retbleed mitigations require extensive changes to the system which results in up to 14% and 39% performance loss on Linux for affected AMD and Intel CPU respectively. [4] The PoC works against Intel Core 6th, 7th and 8th generation microarchitectures and AMD Zen 1, Zen 1+, and Zen 2 microarchitectures.
On July 7, 2019, AMD officially launched their Ryzen 3000 series of central processing units, based on the TSMC 7nm process and Zen 2 microarchitecture. On August 6, 2019, Samsung announced their Exynos 9825 SoC, the first chip built using their 7LPP process. The Exynos 9825 is the first mass market chip built featuring EUVL. [48]
But it's been more than 24 years since AMD's last 2-for-1 stock split on Aug. 22, 2000. On the day before it executed that split, its stock closed at $68.88 a share.
