„AMD Designing Zen 4“ 2021 metams, „Zen 3“ užbaigia projektavimo etapą, pasibaigsiantį 2020 m


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“ mikroarchitektūra yra skirta kitam dideliam procesų technologijos pokyčiui per 7 nm, EUV (ekstremalus ultravioletinis spindulys), kuris leidžia žymiai padidinti tranzistoriaus tankį ir galėtų palengvinti didelius energijos vartojimo efektyvumo patobulinimus, kuriuos būtų galima panaudoti norint padidinti laikrodžio greitį. greičiu ir našumu. Jame taip pat gali būti naujų ISA instrukcijų rinkinių. Kai „Zen 3“ praeis projektavimo etapas, AMD imsis prototipų kūrimo ir bandymo. Pirmieji „Zen 3“ produktai galėtų debiutuoti 2020 m. „Zen 4“ yra skirtas kitai erai. 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.
