"Apple told me MBP maxes out at 16GB RAM because LPDDR3 limit is 16GB/chip; Apple uses it because of performance/energy ratio."

So we've got a cap on RAM because they wanted to make it thinner and lighter, with less space and weight available for battery.

Huh... That's disappointing

LPDDR3, can someone educate me on what this is and why there is such a low cap? Is this some new micro memory technology?

Oh they don't use DDR4? Thats surprising (and annoying), to say the least.

Does LPDDR4 exist? From initial look, the difference between LPDDR3 and DDR3 comes from the lower voltage, though I guess there is some sacrifice with cap on memory? (Please correct if I am wrong)

Max cap on DDR3 is 16GB per module.
Anyone know what the max cap is on DDR4?

They want you to buy the next updated version with a 32gb option.

Probably will arrive 2 years down the road

LPDDR4 exists. Intel just have to support it.

The intel CPUs Apple uses maxes out at 64GB for DDR4, but 16GB for LPDDR3.
