AMD Adds GFX13 Support Signaling RDNA 5

AMD is adding GFX13 support to the LLVM compiler stack, revealing the next-generation GPU architecture will be called RDNA 5 and that a GFX1310 branch targets discrete GPUs. The LLVM change signals early toolchain integration ahead of an expected mid-2027 launch on TSMC's N3P node. The update hints at a Radeon 10000 series and gives driver and ROCm developers time to optimize.
