So one die with 8 cores has access to the normal amount of vcache while another die with 8 cores has access to the normal vcache plus the extra 3D cache
So only one die has 3d vcache. Got it. You kinda have me nerding out on this stuff now. lol.
ETA: It may not be possible, but would AMD consider adding 3d vcache to both die in the future?

Their position was that because current games generally don’t even use 8 cores, adding the 3D vcache to the second die was both an unnecessary cost increase as well as a reduction in performance of that second die.
I think they expected the hand off logic to work better than it does, and in hindsight, I wonder if they regret that decision. They basically have three options: significantly improve the hand off logic, include the vcache on both dies, or simply stop selling the x3D above the X800 chips. Only time will tell which they choose.
