AMD Ryzen 7000 'Raphael' Desktop CPUs will be the world's first 5nm chips powered by the Zen 4 core architecture as officially introduced by the red team. During their Computex 2022 keynote, Dr. Lisa Su (CEO of AMD) confirmed some new details regarding the next-generation platform and its performance uplift versus the Ryzen 5000 'Zen 3' lineup.

The AMD Ryzen 7000 processors will be powered by the brand new Zen 4 core architecture which is going to be a total architecture overhaul. The CPUs will retain the chiplet design along with high-core counts. AMD hasn't confirmed anything in terms of specifications but it is stated that they will be powered by TSMC's 5nm process node and are designed for gamers first. The Ryzen 7000 CPUs will utilize two Zen 4 CCD's (Core Complex Dies) based on TSMC 5nm process and a singular I/O die (IOD) which is fabricated on TSMC's 6nm process node.
