What is the point of those chipsets anyway ? Isn't just better to run without chipset at all, if you're pcb size constrained ?
CPUs are already SoCs..
Looking at the slides, those chipset have no extra usbs and sataSure, if you are willing to give up USB3.1 and the other modern features.
There is not much point in leaving out the I/O expander, since it is pretty nicely integrated chip which requires only a tiny amount of power and has a tiny footprint.

So if those slides are indeed correct, i really don't see the purpose of those.
that would actually make a lot of sense, although i dont get why they have 3 skus for that. Having no dedicated chipset should reduce complexity.One thing I am wondering about if these X300/B300/A300 are indeed chipset-less:
Will it be possible to have a M.2 SSD (2280 form factor) on the front of a Summit Ridge SoC board if it is Mini ITX? (Current LGA 1151 Mini-ITX motherboards have the M.2 SSD on the back of the motherboard)
