And, conveniently, AMD offers X3D (3D V-Cache, a.k.a. a f*** ton of L3 cache) in multiple products, spanning two generations of CPUs and multiple motherboard platforms. If we confine ourselves to AMD’s latest socket, and thus to the Ryzen 7000 Series, we have the Ryzen 7 7800X3D, the Ryzen 9 7900X3D, and the flagship Ryzen 9 7950X3D. And, as good as the ~$350 Ryzen 7 7800X3D is, by all accounts, what happens if we go all out and spring for the Ryzen 9 7950X3D at nearly double the cost??

For one thing, you get a bit of a headache with regard to correctly configuring your Windows system to properly use the 3D V-Cache in the flagship part, due to the split personality of the R9 7950X3D. One CCD has that sweet, sweet 3D V-Cache, and the other does not. The inner turmoil is no doubt the stuff of compelling drama, but PC gamers could probably do without the added complexity involved with properly scheduling CCDs for gaming vs. compute workloads. I’ve whined about this before, and I’m whining about it again, here.
