Ryzen uses the "Zen" CPU microarchitecture, a redesign that returned AMD to the high-end CPU market after a decade of near-total absence since 2006. [5] AMD's primary competitor, Intel, had largely dominated this market segment starting from the 2006 release of their Core microarchitecture and the Core 2 Duo. [6]
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 ...
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).
Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. [4] [5] [6] It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs. [7]
Zen 3 is the last microarchitecture before AMD switched to DDR5 memory and new sockets, which are AM5 for the desktop "Ryzen" chips alongside SP5 and SP6 for the EPYC server platform and sTRX8. [3] According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 2.
The K6 was generally pin-compatible with the Intel Pentium (unlike NexGen's existing processors). AMD K6-2 – an improved K6 with the addition of the 3DNow! SIMD instructions. AMD K6-III Sharptooth – a further improved K6 with three levels of cache – 64 KB L1, 256 KB full-speed on-die L2, and a variable (up to 2 MB) L3.

The line aimed at competing with the Intel Core line of desktop processors, in particular processors based on Sandy Bridge and Ivy Bridge architectures. [2] [3] FX has been succeeded by the Ryzen brand of CPUs, based on the Zen architecture, which initially launched in 2017 to compete with Intel's later generation processors such as Skylake. [4]
