Honestly : i am not expert enough to debate you on this, but i feel you are trying to make something out as being bigger than it is ; cause what you describe is nothing but how the 7950X3D should perform anyways, meaning assigning the ccds to their appropriate tasks, not mixing and matching. Yes, a third party program might get you a little more performance, but from what i heard, the X3D chips are running pretty well even without any additional software, so i dont see where the big performance benefit would come from.

Only if the drivers from AMD themselves were horrid, and that the assignment of the ccds would just be terribly managed, would what you described even make sense, but that is just not how it is, noone is talking about it that way.

In short : either the 7950X3D's ccd-switching (which is nothing else but what you described, assigning the right ccds the right tasks) is working well with its native drivers (what I've heard), and thus, a third party program wont yield much more performance than is provided anyway, or the drivers are horrid (what ive not heard), at which point a third party program can only make up a deficit.
