It looks like AMD is heavily investing in stacked cache and chiplet technologies for their next-gen CPU & GPU designs. Based on a new rumor by Greymon55, it looks like after EPYC & Ryzen, AMD will be bringing stacked 3D Cache design to RDNA in the form of 3D Infinity Cache.

With RDNA 2, AMD introduced its first-generation Infinity Cache architecture which is a fast and high-bandwidth on-die cache that the GPU can quickly access. The existing cache designs can be scaled up to 128 MB capacities and up to 2 TB/s bandwidth. With next-gen RDNA 3 GPUs, it has been rumored that the GPUs will double the amount of Infinity cache with Navi 33 expected to offer 256 MB and Navi 31 expected to offer up to 512 MB of Infinity Cache.
