Re: AMD demos Ryzen 9 5900X prototype with added 3D V-Cache
Both AMD and Intel have talked about the use of such stacking,but the bigger issue is going to be cooling each layer sufficiently. Is the extra cache on top of the existing cache locations on the chiplet?? It would make sense of the copper connection layer to be over the cores??
I might not be serious.

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


AMD s 3D V-Cache chiplet tech enters production later this year
on June 1, 2021, 11:15
In brief: AMD caught everyone off guard at Computex 2021 with a demonstration of its new 3D chiplet technology that looks to deliver the type of performance gain you’d typically see with a new process node or microarchitecture.
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.
AMD CEO Dr. Lisa Su showed off a prototype Ryzen 5000 CPU with one of two chiplets featuring the added stacked cache. As AnandTech highlights, the difference is obvious compared to the standard chiplet. The 3D V-Cache die is not as large as the core die, so AMD added additional structural silicon for support. Both dies were also thinned, meaning AMD doesn’t hav ....

AMD patents active bridge chiplet design with integrated cache for next-gen GPUs


AMD is planning to introduce an active bridge chiplet with integrated cache on an upcoming GPU architecture. A new patent filed by the company has been spotted describing the use of the active bridge chiplet, which seems to offer a significant upgrade over the passive bridge chiplet design showed earlier this year.
According to the patent shared on Reddit by u/marakeshmode, the active bridge chiplet would work an intercommunication lane across the chiplet dies. This would also feature a shared L3 cache buffer for all compute units, similar to Infinity Cache on Radeon RX 6000 series GPUs.
The patent further explains that any communication made between the GPU chiplets would go through the active bridge chiplet. For developers, the new GPUs would work as a single, monolithic GPU, ignoring any chiplet-specific considerations from older MCM designs. ....
