DX12 will allegedly enable mixed configurations of AMD and Nvidia GPUs to work together through the explicit asynchronous multi-GPU feature. This was revealed in a recent article by Tom’s Hardware, in which the website claimed through some of its own sources that Microsoft’s upcoming DirectX 12 API will enable cross-vendor multi-GPU configurations...

.. This also means that if you have two 4GB GPUs you will in fact get 8GB of usable graphics memory instead of just 4GB like you do right now. This is because instead of tasking each GPU with rendering a whole frame on its own, each GPU would actually render different parts of the same frame. Which in turn negates the need of having to mirror the resources in the two separate memory pools of the cards. This is the limitation behind the alternate frame rendering technique used today that prevents developers from addressing the two separate memory pools as a larger single pool of graphics memory.
