Well I am not sure who you are replying to or what you mean by "3DCache has zero effect on CCD's", but my point still stands... this new 3D cache is only on one of the CCDs of the new dual CCD CPUs like 7950X3D. This means that all 16 cores of this CPU are no longer equal in performance like they were in previous AMD CPUs like the 5950X . You now have 8 faster cores (16 threads) on 3D cache CCD, and 8 slower cores (16 threads) on normal CCD. So there is a big difference there compared to older CPUs. And probably something they don't want buyers of new 3D cache CPUs to know about.
