It has been previously reported that AMD's next-generation Ryzen 6000 series processors, codenamed Warhol, based on the Zen 3+ architecture and using a 6nm process, have been canceled and will be replaced by the XT/Refresh version of the Zen 3 architecture. This is likely to be the last update to the Ryzen family for the AM4 platform, along with the release of the X570s chipset, which will be announced later this year. The reason is that current market supply conditions, as well as TSMC's capacity conditions, prompted AMD to abandon Warhol and focus on the next-generation processor, codenamed Raphael, which will be built using a Zen 4 architecture and a 5nm process.
AMD is likely to integrate rDNA 2 architecture core display on the Ryzen 7000 series, codenamed Raphael, with the new AM5 platform, which will support PCIe 5.0 and DDR5 memory, and its I/O chip will be upgraded to 6nm process. According to Twitter user @sepeuwmjh, AMD will announce a new platform in Q3 2022, followed by a Zen 4 based Ryzen family of processors that will compete with Intel's 13th Core family, codenamed Raptor Lake-S desktop processor, in Q4. With a long way to go before the official release, AMD still has plenty of room to tweak.
