Too many factual errors in the article. Many of the comparisons state DDR3 - but DDR4 is not DDR3.
> the difference of power draw between DDR3 and DDR4 is almost negligible.
It's NOT. The article he's citing mentions IDLE standby power consumption. Not the same thing as active power consumption.
- Correction: Power draw of DDR4 and LPDDR3 is very similar under active usage (i.e. not in standby). DDR4 might be possibly slightly lower.
I couldn't find a direct comparison, but according to Samsung:
* LPDDR3 vs DDR3L uses 15% less power in operation [1]
* DDR4 vs DDR3L uses 37% less power [2]
- Correction: LPDDR3 is much more efficient for STANDBY (yes, you can have that 30 days standby). [3]
So without LPDDR3, in my opinion, the standby of MBP would be reduced to ~15 days from 30 days (haven't done proper calculations but it's roughly half). But it wouldn't matter in normal usage.
I still believe Apple didn't consider DDR4 due to size concerns as even SODIMM DDR4 on the logic board would larger.
