AMD may restrict the RDNA 3 architecture only to top-tier Navi 3x offerings such as Navi 31, Navi 32, and Navi 33, according to a new leak. SKUs from Navi 34 onwards may use a 6 nm refresh of the Navi 24, Navi 23, and Navi 22. Only Navi 31 and Navi 32 are currently expected to feature an MCM design.
