A little over a week ago, an AMD patent titled Distributed Geometry was published by the US Patent Office, the patent itself was filed by AMD in April this year. The patent details a fully chiplet approach to GPUs, where the rendering workload is distributed across a collection of chips, rather than having one massive die handling all of the processing. There's no indication that we'll see this employed in a Radeon graphics card any time soon, of course, but it's the natural evolution of what we've already seen in RDNA 3.
I picked up news of the patent from YouTube channel RedGamingTech and it's a fascinating read. Although the document is titled 'Distributed Geometry', it's really about distributed rendering. Take AMD's current Navi 31 GPU, its largest graphics processor as used in the Radeon RX 7900 series. That does use chiplets but these only contain two VRAM interfaces and a slice of L3 Infinity Cache; the rest of the GPU resides in a single block (called the GCD, graphics compute die).
