The transition of the Ryzen 3000 processors to the B0 stepping means that AMD has already finalized and improved its new generation chips. As you know, during the development process, manufacturers find errors in their processors and, correcting them, release chips on new steppings. Usually everything starts with A0 stepping, which corresponds to the first chips created in the laboratory. Then there are steppings A1 and A2, which can be considered minor updates with minor improvements and fixes.
