AMD's next-generation Ryzen 4000 CPU family which will be based on the 7nm+ Zen 3 architecture is reportedly arriving at the end of 2020. The report comes from MyDrivers who have received info from their sources that the new processors and the accompanying platform will be available by the end of 2020.

The report talks about two next-generation AMD products, the AMD Ryzen 4000 desktop processor lineup and the 600-series chipset based platform. The AMD Ryzen 4000 CPU lineup will feature the enhanced 7nm+ Zen 3 core architecture. The 7nm+ EUV technology will uplift the efficiency of Zen 3 based processors while increasing the overall transistor density however the biggest change to the Ryzen 4000 series processors would come from the Zen 3 core architecture which is expected to bring a brand new core design to the architecture, allowing for significant IPC gains, faster clock speeds and higher core counts.
