In 2016, the company AMD introduced the AM4 socket for the then Zen architecture and promised to support it until 2023 inclusive. At the moment it is compatible with processors up to the line Ryzen 3000. However, it has now become known that support will appear for Ryzen 4000.
At the same time, AMD said that it does not plan to introduce support for the Zen 3 architecture for older chipsets, since there BIOS chips are limited in volume.
Thus, although formally the processors will be fully compatible with motherboards based on the AM4 socket, in fact you will have to choose one of the relatively new models. As noted, motherboards with the AMD B550 chipset will appear on June 16th. They will receive support for PCIe 4.0 and other technologies.
