With competitive GPUs, Intel has all bases covered (CPU, GPU, FPGA, and so on). They primarily intend to shove their GPUs in laptops by leveraging their clout with OEMs and to use them in data centers, the client dGPU market is irrelevant in comparison. Gotta agree with Glo., there is no bright future for client dGPUs. Wait until we get to 5nm and beyond! The costs for bringing a single chip to market will be insane, and at some point it won't even be economically viable to do so. Since it is a much smaller market and a chiplet approach with GPUs is much more difficult than with CPUs, the client dGPU market will reach that point first.
These prices are just the beginning. With Navi, AMD showed that they aren't interested in lowering margins in an attempt to grab a bigger piece of the relatively small GPU market pie from Nvidia, and I highly doubt that Intel will be any different. There being three players will just mean lower volumes for everybody, and coupled with how increasingly expensive it's getting for them to develop GPUs, I don't anticipate lower prices anytime soon.
