This is also for you, andybird123.
For example, Intel could license a Kepler design to incorporate as their IGP. (Not that I think will happen)
It stands to reason that Nvidia will have to adapt, maybe this is them trying?
I'm literally guessing though.
Right

Intel are pretty confident in their own tech.
Nvidia are experiencing a double pronged attack from both Intel and AMD in this space.
Nvidia sell a lot of low and mid level discrete GPU's to OEM's, with AMD and now Intel making Integrated GFX that are just as capable as Nvidia's low to mid level OEM GPU's, those OEM will chose the cheaper more power efficient, more convenient integrated option over Nvidia's OEM GPU's.
Intel nor AMD will take up Nvidia's tech to integrate into their CPU's, whats more anyone wanting to make x86_64 capable CPU + GPU's in that space will also need the blessing of Intel and AMD who own all the needed IP.
That leaves those already licencing ARM CPU's to then also licence Nvidia GPU tech to integrate and make their own 'APU's'
Intel and AMD have very capable solutions in the ARM space with their own iGPU's, and Nvidia already licence ARM and integrate their GPU's to make Tegra. a Samsung licenced ARM chip with an Nvidia iGPU is just another competitor for AMD, Intel and Nvidia.
Perhaps Samsung might want to make their own version of a GTX 680?
Whose that going to hurt? Nvidia more than anyone.
Perhaps Nvidia think licencing their GPU tech along with CUDA will flood the market with CUDA enabled products, there in negating OpenCL's momentum.
Scenario A: Intel and AMD also take up CUDA and simply integrate it into their existing tech.
The GPGPU market is open, more players can enter, we all benefit and none of the big 3 have any advantage over the other.
Scenario B: Nvidia refuse licencing to Intel and AMD, instead licence to others CUDA and GPU tech to flood the market with CUDA only enabled products on a very narrow part of the market where they don't need Intel - AMD's blessing.
This might hurt Intel and AMD in the growing mobile GPGPU space, a tiny bit.
I think it far more likely developers by enlarge will not back it as the other two big players with the majority of combined market share are incompatible.
No developer wants to sell a product that does not work for the majority of its user base.
