The reason was the dissatisfaction of users, because the boards use the same AM4 socket. And the company itself promised support and backward compatibility until 2023.
The company issued a press release in which it stated that motherboards based on the B450 and X470 logic will work with Ryzen 4000 processors, but with some reservations. The bottom line is that the memory capacity of BIOS chips is not always able to accommodate new firmware with support for future processors. Because support for new chips will replace the old ones in microcodes
Given this, an interesting situation will turn out – when installing the new BIOS firmware on compatible boards, only Ryzen 4000 can be launched, older models simply will not work. And you can’t roll back the BIOS to the old version.
The company plans to distribute such firmware only at the request of users, and not centrally. Most likely, the company will demand evidence that this or that user bought the “four thousandth” processor.
It is important to note that the fifth generation of Raisen will receive a new socket, which will differ from AM4.
