So I've seen recently that is now possible with DirectX 12 to put AMD and Nvidia GPU'S together in SLI/Crossfire which is terrific. I've also seen that you can Crossfire an APU's GPU with older AMD GPU's like the HD 7850. So this got me thinking, is it now possible to get the GPU form the APU and pair it with a newer AMD card or with a Nvidia card? If so what problems would this cause if any and would you see any performance improvements?
Time will tell. In theory, if DX12 truely delivers on this front, yes, we'll be able to do such asynchronous configs and benefit from them. Furthermore, this may prove as a great way to reduce energy consumption. Case in point, one migh fully shut down a discrete GPU and only use the APU in windows, whiile waking the "monster" up when needed. Even if there were no performance improvements whatsoever, i would still go for such a config. Even intel iGPU+discrete AMD/NVIDIA.(this has been unsuccesfully attempted by Virtu in the past)
