I'd sure like to see the usage scenarios in which these products compete with each other and the LPDDR4 gives a performance advantage. The picture will surely get even muddier once you consider the Core i7 in SP4 comes with eDRAM cache, bringing quite a change in effective memory bandwidth.Skylake/Kaby Lake tablets (pretty much just the Surface Pro 4 if I'm honest) were slightly handicapped by the lack of LPDDR4 relative to the competition like the iPad Pro.
