The first die block diagram of AMD's Ryzen 5000 'Cezanne' CPUs based on the Zen 3 architecture has been leaked by Videocardz. The block diagram shows that AMD's Ryzen 5000 'Cezanne' APUs will be sporting some major design changes and are not just a general refresh of the existing 3rd Gen Ryzen 4000 'Renoir' APUs.

AMD's Ryzen 5000 'Cezanne' CPUs will be based on the Zen 3 core architecture which brings huge gains in IPC and efficiency. It is based on an optimized TSMC 7nm process node but the key Zen 3 changes have mainly been the restructuring of the cache design along with integral core upgrades.
