Quote:The "Zen 3" microarchitecture is designed for the next big process technology change within 7 nm, EUV (extreme ultraviolet), which allows significant increases in transistor densities, and could facilitate big improvements in energy-efficiency that could be leveraged to increase clock-speeds and performance. It could also feature new ISA instruction-sets. With "Zen 3" passing design phase, AMD will work on prototyping and testing it. The first "Zen 3" products could debut in 2020. "Zen 4" is being designed for a different era.
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.
