AMD Designing Zen 4 for 2021, Zen 3 Complets Design Phase, out in 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 microarchitecture `` Zen 3 '' est conçue pour le prochain changement technologique majeur dans les 7 nm, EUV (ultraviolet extrême), qui permet des augmentations significatives de la densité des transistors, et pourrait faciliter de grandes améliorations de l'efficacité énergétique qui pourraient être utilisées pour augmenter l'horloge. vitesses et performances. Il pourrait également comporter de nouveaux jeux d'instructions ISA. Avec le passage de la phase de conception «Zen 3», AMD travaillera sur le prototypage et le testera. Les premiers produits «Zen 3» pourraient faire leurs débuts en 2020. «Zen 4» est conçu pour une autre époque.

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.
