AMD Designing Zen 4 for 2021, Zen 3 Completes 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+.'

Zen 3-mikroarkitekturen er designet for neste store prosessteknologibytte innen 7 nm, EUV (ekstrem ultrafiolett), som tillater betydelige økninger i transistortettheter, og kan lette store forbedringer i energieffektivitet som kan utnyttes for å øke klokke- hastigheter og ytelse. Den kan også inneholde nye ISA instruksjonssett. Med 'Zen 3' bestående designfase, vil AMD jobbe med prototyping og testing av den. De første 'Zen 3' -produktene kunne debutere i 2020. 'Zen 4' er designet for en annen epoke. 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.
