KGI Securities analyst Ming-Chi Kuo claim in a research note published on Friday that the new Apple MacBook pro is updated with Kaby Lake processors as well 32GB of RAM upgrade. The ”MacBook”  production will start in the fourth quarter, which starts in September .

Apple’s MacBook Pro 2016 model was highly criticized as the company didn’t make any change in hardware and it stick with 16Gb RAM and Intel’s older Skylake processors .

Apple later make a statement about the reason that they carry with 16GB of RAM because that was the available and highest capacity with LPDDR3.

If Ming-Chi Kuo claim is said to be true than  Kaby Lake SKUs are consistent with LPDDR4,

Although Intel spec sheets didn’t mention or confirm the compatibility of  LPDDR4 with 7th generation Kaby lake processor .The current  Kaby Lake processor are design to assist few combination of DDR4, LPDDR3, and DDR3L, and  no indication of LPDDR4 support.

If you don’t know the difference between the three division, the following chart from Synopsys lays out the DDR3 specification differences.

the values are different for DDR4,which give the basic idea that  DDR4 draws the most power, DDR4L is a power-optimized version of DDR4, and LPDDR4 is its own unique feature which reduced standby power consumption.

As shown in the graph,

20nm DDR4 took four year to upgrade from 40nm DDR3 .LPDDR4 is suppose to consume approximately 62% as much power as LPDDR3, that indicate the 32GB of LPDDR4 will pull more power than 16GB of LPDDR3, unless Apple reduce the clock speeds or uses specially binned LPDDR4 RAM for minimal power consumption. DRAM remains active when the system is online which means having 32GB of ram it will cause some concern for  battery time compared to 16 GB.
