The next generation of Radeon GPUs from AMD are expected to be a significant upgrade over RDNA 4, and one of the issues Team Red seems to be tackling is dual issue execution. That's the GPU's ability to execute two instructions in the same cycle — AMD's cards have had this feature since RDNA 3, but strict pairing rules meant that compilers couldn't always take advantage of it, limiting theoretical peak performance. A new LLVM patch now suggests that AMD will be solving this on RDNA 5.
