It is expected that in the fourth quarter
At least, under the symbol Vermeer, the fourth generation of Ryzen desktop processors may appear next year, and from this point of view, everything is logical. It remained to understand what family of processors is hidden under the designation Genesis. The German source makes the assumption that the full designation of this family of processors is “Genesis Peak”, and it also fits into the “mountain theme” of Ryzen Threadripper processors. In a particular case, we are talking about fourth-generation processors, which will definitely not appear before next year. Genesis Peak is a mountain peak in the same state of Washington as Castle Peak. The current generation of Ryzen Threadripper processors, which is the second in a row, bears the designation "Colfax", also related to the mountain range in this state.
What innovations will provide fourth-generation Ryzen Threadripper processors, one can only guess. We can only assume that it will use the Zen 3 architecture and the second generation of 7nm manufacturing technology. As for compatibility with existing motherboards, nothing can be said with certainty either. Perhaps by the end of next year, the issue of PCI Express 5.0 support will not be so acute yet, so Ryzen Threadripper processors will be content with previous versions of the interface.
