Does anybody know how many of these could we expect to fit in a Macbook Pro? My understanding is the power consumption has been a limiting factor.

You can fit exactly zero of these in the MacBook Pro until Intel ships chips that actually support LPDDR4X (aside from the Cannonlake paper launch).

Or Apple switch them to the A series processors! Although I really cannot see that happening on the pro lineup anytime soon (Although I think its highly likely on the air and non-pro MacBooks)

I read somewhere that it wouldn't actually help at the moment. LPDDR4 on the A series chips is in the same package as the CPU. From what I understand, this is the only current way that anyone in the industry is using LPDDR4.

What Intel is promising is LPDDR4 packaged in it's own chip(s) on the motherboard.

In the iPads, the RAM is not stacked onto the CPU, it's normal separate chips. e.g. two Micron here: https://d3nevzfk7ii3be.cloudfront.net/igi/WHKDR5ZU6SSQA3qa

Had to double check that....but you're correct. So now I'm really hoping for a AX macbook pro. Imagine what the A12X in the newest ipad could push if you added some nice cooling to it ;)

As long as you aren't using any Adobe software.

So I wonder if Micron will support 16Gbit LPDDR4X chips by the time Intel launches its 10nm chips.

they have 16 Gbit LPDDR4 from what I know

I am talking about the capacity of the individual die BTW.

1. zero because Intel still has no support for LPDDR4 in their laptops

2. I don't know that it would make much difference, IIRC energy-efficient RAM has a huge impact on idle/sleeping power, but when everything's running full tilt other components way outdraw RAM's needs

Apollo lake and Gemini lake support regular LPDDR4. I bet, you can make it use LPDDRX timings.
