It appears that AMD prefers calling the next-gen GPU architecture "RDNA 5" instead of UDNA and the latest leak confirms it.
AMD Adds GFX13 Support to LLVM, Hinting at Early RDNA 5 Work Ahead of Next-Gen GPUs Release
It looks like AMD will be calling its next-gen architecture "RDNA 5" and not UDNA. We have seen both naming schemes in previous reports, but the latest leak points towards AMD continuing the RDNA naming convention for its upcoming GPUs. As spotted by @Kepler_L2, the new documentation updates in the LLVM compiler stack reveal initial support for the GFX13.
GFX13 is the ID for the next-gen GPUs, and its GFX1310 branch points towards the discrete GPU lineup. Since the GFX13 has been explicitly shown in the documentation as linked to the RDNA 5 architecture, the GFX1310 is going to be the Radeon 10000 series if AMD continues the current Radeon GPU naming convention. Keep in mind that while such enablements or entries may not mean much, these are the early works needed to be done for proper optimizations when the products launch.
LLVM is a critical component of AMD's GPU software ecosystem for the Linux graphics drivers, Mesa, ROCm, and similar development tools. When a GPU architecture is added to LLVM, it indicates that it is now ready for toolchain integration. As far as the existing AMD architectures are concerned, the GFX12 ID ends with the RDNA 4 GPUs, and therefore, the GFX13 is a major ID change in the LLVM.
The RDNA 5 GPUs aren't likely to come before 2027 and will utilize the TSMC N3P node. The launch is expected in mid-2027, which will coincide with the launch of NVIDIA RTX 60 series Rubin GPUs. Not much is known regarding the product stack, but hopefully, AMD will resume the fight in the higher-end segment unlike the RDNA 4 GPUs.
