The idea of another competitive GPU manufacturer is nice. But it is hard to bring into existence. Intel is not in a position to invest lots of money and sustained effort into products for which the market is captured and controlled by a much bigger and more competent company on top of its game. Not even AMD can get more market share, and they are much more competent in the GPU technology. Unless NVIDIA and AMD make serious mistakes, Intel GPUs will remain a 3rd rate product.

Intel has big problems and it's not clear they should occupy themselves with this. They should stabilize, and the most plausible way to do that is to cut the weak parts, and get back to what they were good at - performant secure x86_64 CPUs, maybe some new innovative CPUs with low consumption, maybe memory/solid state drives.
