Does Hybrid-SLI use the IGPU to assist the GPU?

    Quick question about Hybrid-SLI rumored to be in the new MBPs. I know there's this swapping mechanism to turn off the dedicated GPU when on the go to improve battery life, but will having an IGPU and a GPU with Hybrid-SLI allow the IGPU to boost graphics performance when plugged into the wall by working with the GPU? If so, by how much? Would you notice the difference between a 9650M GT on it's own and with a IGPU alongside?

    Normally this would be the case but SLI does only work under Windows.
    If the GPU is quite capable the difference would be negligible at best.

    If the new 9400M is going to be present in the new notebooks maybe it'll make a worthwhile difference. Presumably Apple would bother to enable this on OS X, but it'd be beneficial to me anyway via. Bootcamp gaming.

    Here's hoping.

    If you had read up on it using the Nvidia sight instead of asking a silly question, you'd have found this:

    Read the Hybrid Power and GeForce Boost sections. They both fall under the Hybrid SLI umbrella.
