But this time they're actually making a play for the discrete graphics market. They've hired Raja Koduri and everything. Not the first time they've done that either (see: Larrabee) but they do look to be making a serious attempt.

Having a discrete graphics die, and especially having access to HBM2, makes a huge difference in performance. There isn't much you can do with 30 GB/s of bandwidth to share between CPU and GPU. Having Crystal Well L4 cache is a huge boost but it's still a halfassed fix compared to having proper VRAM available.
Of course, it's also a vastly more expensive part as well. Just the CPU+GPU package is more expensive than some of the 2500U laptops.
Presumably Intel is aiming for something more like Vega M GH with Jupiter Sound/Arctic Sound - it makes little sense to design a low-end discrete part with no room for future performance growth.
