Simultaneous multithreading (SMT) is a technique for improving the overall efficiency of superscalar CPUs with hardware multithreading. SMT permits multiple independent threads of execution to better use the resources provided by modern processor architectures .
In addition, all support Simultaneous Multithreading (SMT) except earlier Zen/Zen+ based desktop and mobile Ryzen 3, ... 6 (6) 2.3 Ryzen 3 4300U [c] 4 (4) 2.7
Included in the Ryzen and Epyc CPU lines. AMD Zen Family 17h – first generation Zen architecture based on 14 nm process. First AMD architecture to implement simultaneous multithreading and Infinity Fabric. AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm).
The Ryzen 7020 series targets the "everyday computing" segment. [79] It is a new Zen 2 design based on 6 nm process and RDNA 2 integrated graphics. The Ryzen 7030 series is a refresh of Ryzen 5000 series processors codenamed "Barcelo-R", [80] targeting the "mainstream thin-and-light" segment. [79]
The modular architecture consists of multithreaded shared L2 cache and FlexFPU, which uses simultaneous multithreading. Each physical integer core, two per module, is single threaded, in contrast with Intel's Hyperthreading , where two virtual simultaneous threads share the resources of a single physical core.
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).
