Geforce 800 series to contain integrated ARM CPUs

didn't see much on this topic specifically, and any articles on the subject were vague at best.

What exactly does this do for Nvidia Chips besides turn them into a mini APU? I mean I know roughly the idea behind an APU and what AMD is trying to do with their Fusion thing, but now that Nvidia is doing something similar how different could it be?
To my understanding because it's just a small 64 bit ARM core that's being integrated, it won't replace a conventional desktop CPU but rather help with processing, but I'm not exactly sure to go from there...

I'm asking because I have no clue and would like someone to provide some insight or education :) Thanks community

looks like it is trying to offload some of the cpu demands of a system. im no expert but it seems to me the coding for such a thing would be pretty extreme. it doesnt seem like it would be simple at all.

i personally question any real world gains from such a move too. though, if your cpu was a bottleneck, any assistance at all would result in fps gains.

i almost have to wonder if it has something to do with tegra (even though it is also in pc discrete cards.)
