1. AMD has filed a patent for a future GPU architecture that uses a 'multi-chiplet' design, which could be featured in RDNA 5. 2. The patent describes three different modes of chiplet utilization, including 'single GPU' mode, 'independency mode', and 'hybrid mode'. 3. The multi-chiplet approach allows for flexible and cost-effective configuration of GPU resources, and can be used to assemble multiple different GPUs with varying numbers of chiplets.
