    If manufacturer's started to use unified vram on their cards when in sli or crossfire in theory each card will use its own video memory so your vram would be higher. Could this be done?

    in single card configuration, there will be a lot of problems of syncing between the two RAM in terms of speed and latency..
    I dont expect it to be used in multi gpu for now..

    I believe it is in fact on Nvidia's road map, but no time soon.

    No, not at all.

    Unified memory address across host (CPU) memory and device (DGPU) memory is software feature. (NV Maxwell does have a little bit of hardware support for this, but that's only to address some complications made in previous NV cards.) It helps programmers, but does not change the physical capability of the system. Sharing VRAM across multiple DGPUs is not practical for gaming purposes, and whether you have a unified logical memory pool or not is irrelevant.


    The HSA/HUMA feature on the AMD APUs is a completely different concept.
