Skylake does not support LPDDR4, nor does Kaby Lake (except with their ultra-low power chips).

I don't think we're going to see 32 GB RAM in the ultrabook category until LPDDR4 is supported by Intel in their mobile-class processors.

Edit: AnandTech suggests that LPDDR3 is 25-30% more power efficient than DDR4. (http://www.anandtech.com/show/6326/additional-details-on-mic...)

That might be so, but the macbook air is the ultrabook series and the mac book pro should be the work horse series.

I have a Dell Precision 5510 that supports up to 32GB of RAM and also has Skylake Mobile Xeon. Alas, it is plagued with tons of issues.
