#3.5D GPU

AMD appears to be developing a new generation of GPUs that could revive multi-chiplet designs for consumer gaming. According to the LinkedIn profile of AMD senior fellow Laks Pappu, the company is working on “competitive 2.5D/3.5D chiplet-based and monolithic graphic SoCs” for future Radeon GPUs. This suggests that AMD's next-gen RDNA 5 graphics cards, codenamed Navi 5x, could include more advanced packaging technologies, potentially introducing multi-tile GPU designs to the mainstream market. Pappu joined AMD in 2022 after decades at Intel, where he worked on GPU designs like DG1 and Alchemist, as well as experimental multi-tile architectures. He now leads efforts on future Radeon and data center GPUs, including those built for cloud gaming and AI. Currently, AMD's top-end consumer GPU, the Radeon RX 9070 XT, competes with Nvidia’s mid-range RTX 5070 Ti. Developing a chiplet-based GPU for gamers is far more complex than for CPUs. GPU tasks require tight coordination across thousands of threads, and any latency between tiles can hurt performance.
