AMD's current generation of graphics cards is based on RDNA 3, with the upcoming RX 8000 series set to feature RDNA 4. However, leaks suggest that RDNA 5 is not in the works. Instead, AMD will be introducing UDNA after RDNA 4, streamlining their GPU roadmap. According to a reliable source on the Chiphell forums named zhangzhonghao, the UDNA-based RX 9000 series and Instinct MI400 AI accelerator will both incorporate advanced Arithmetic Logic Unit (ALU) designs, reminiscent of AMD's earlier GCN architectures. Rumors also suggest that Sony's PlayStation 6 will adopt UDNA technology, following the PS5 and PS5 Pro which currently use RDNA 2.
The PS6's CPU configuration is still uncertain, with speculation pointing towards Zen 4 or Zen 5 architectures. The first UDNA gaming GPUs are expected to go into production by Q2 2026. Meanwhile, AMD's RDNA 4 GPUs are expected to target the entry-level to mid-range markets, potentially saving high-end offerings for the UDNA generation. This strategic decision allows AMD to focus on refining AI-accelerated technologies like FidelityFX Super Resolution (FSR) 4 to compete with NVIDIA's DLSS.
AMD's move towards unification is influenced by NVIDIA's CUDA ecosystem, which promotes cross-platform compatibility. By consolidating their architectures, AMD aims to address challenges related to memory subsystem optimizations and compatibility issues. Instead of investing in RDNA 5, AMD is focusing on UDNA as the next step. The company is also expanding ROCm software support across all products, from consumer Radeon to enterprise Instinct MI, to accelerate software development across their entire product range.
