AMD Designing Zen 4 per al 2021, Zen 3 finalitza la fase de disseny, que va sortir el 2020



AMD in its 2nd generation EPYC processor launch event announced that it has completed the design phase of its next-generation 'Zen 3' CPU microarchitecture, and is currently working on its successor, the 'Zen 4.' AMD debuted its 'Zen 2' microarchitecture with the client-segment 3rd generation Ryzen desktop processor family, it made its enterprise debut with the 2nd generation EPYC. This is the first x86 CPU microarchitecture designed for the 7 nanometer silicon fabrication process, and is being built on a 7 nm DUV (deep ultraviolet) node at TSMC. It brings about double-digit percentage IPC improvements over 'Zen+.'

La microarquitectura 'Zen 3' està dissenyada per al pròxim gran canvi de tecnologia de processos dins de 7 nm, EUV (ultraviolada extrema), que permet augmentar significativament les densitats de transistors i podria facilitar grans millores d'eficiència energètica que es podrien aprofitar per augmentar el rellotge. velocitats i rendiment. També podria incloure nous conjunts d'instruccions ISA. Amb la fase de disseny “Zen 3”, AMD treballarà el prototipat i la prova. Els primers productes 'Zen 3' podrien debutar el 2020. El 'Zen 4' està dissenyat per a una època diferent. The 'Zen 4' architecture is being designed for a 2021 market debut, and will come out at a time when the 7 nm process will have matured and attained high enough volumes at TSMC for AMD to either build bigger dies (more cores per chiplet), or leverage the even more advanced 6 nm EUV node. The maturity and volumes of these sub-10 nm nodes could change the economics of the MCM approach AMD is undertaking for its EPYC processors.
