TechUp: AMD shows off stacked 3D V-Cache chiplets, resulting in up to 192MB of L3 cache TechSpot

Developed in collaboration with TSMC, AMD’s first application of the 3D chiplet tech is a vertical cache addition for its high-end processors. In a nutshell, AMD used a process called through-silicon vias (TSVs) to stack additional L3 cache on top of the compute chiplets.
