AMD is planning to replace RDNA, the current code name for its Radeon GPU microarchitecture, with a new one dubbed “UDNA” after the RDNA 4 generation, according to the latest rumors that have surfaced out of China. The new claims, which stem from Chiphell insider zhangzhonghao, also include the idea that the PlayStation 6, Sony’s next-generation console, will be one of the earlier devices to leverage the UDNA architecture. Microsoft is additionally said to be considering Qualcomm or AMD chips for its Xbox handheld.
There is no RDNA5 code name. After RDNA4, it will be UDNA. MI400 and RX9000 use the same UDNA, and the architecture uses an ALU design similar to GCN. UDNA Gaming GPU is tentatively scheduled for mass production in Q2 26. Sony’s PS6 will use UDNA, and the CPU has not yet been determined to be ZEN4 or ZEN5. Sony’s handheld will also use AMD hardware. I heard that Microsoft’s handheld will choose between Qualcomm and AMD? I don’t know about this The above information comes from the supply chain, and I don’t know the specifications and performance.
