The last generation of construction cores did split silicon, with a 2 core/3 CU parts targeted at the entry level market and a 4C/8CU part for the mid-range. Drop to half the cores, 3/8 of the shaders and half the memory channels and you're going to save well over half the silicon area - and therefore you're going to half the cost as well. And for Raven Ridge, that goes up to 3/11 of the IGP - an even bigger silicon saving.

The only reason to salvage a part this hard is if you'd otherwise have to bin them, which implies that there's a real problem yielding the IGP on Raven Ridge. There's more than twice as many disabled shaders as active ones. That's .... odd, frankly.
