AMD engineers announced the completion of work on the Zen 3 architecture, involving the manufacture of processors for 7-nanometer technology. Now experts have started to design Zen 4, work on which they plan to complete in two years.
The current microarchitecture used in the third-generation Ryzen desktop chips is Zen 2. It also serves as the basis for the second-generation EPYC server processors and is considered the first x86 microarchitecture, which was developed taking into account the specifics of TSMC plants.
Zen 3 already uses extreme ultraviolet lithography, which increases the density of the layout and the number of connections, significantly increasing the energy efficiency of processors with increasing clock speeds and power.
Given the completion of work on Zen 3, the first chips built on this microarchitecture may appear on the market in 2020. Testing prototypes Zen 4 AMD plans to start in 2021-M. it is possible that in two years the semiconductor industry will switch to more sophisticated methods of making chips, and AMD will completely revise the approach to the microarchitecture.
