At its Next Horizon event in San Francisco, AMD announced the fourth iteration of its Zen microarchitecture. The Zen 4 is currently in development, so the company does not share many details about it right now.

Right now, the company is sampling its codenamed Rome CPUs based on Zen 2 microarchitecture and made using TSMC’s first-generation 7 nm manufacturing technology (N7). After that, AMD plans to release a processor based on its Zen 3 architecture and these chips will be made using TSMC’s N7+ fabrication process that will take advantage of EUV lithography. Since Zen 4 microarchitecture is still in design phase, chances are that processors on its base will be made using a more advanced node, so think 5 nm, but keep in mind that any guesses today are speculations at best.

Previously AMD has only discussed Zen 2 and Zen 3 microarchitectures, yet it is not surprising that the company will keep evolving its successful design in the coming years.

This is a breaking news. We are updating the news story with more details.
