New Apple MacBook Pros are great laptops, but like with every product in the world, there is at least one drawback. The revamped MacBook Pro supports only 16 GB of RAM, and Apple will less likely launch a version with more RAM as that would compromise the MacBook Pro’s design.
Apple’s SVP of Worldwide Marketing Phil Schiller already explained why new MacBook Pros don’t support 32 GB, but Apple fans are not stopping with questions of 32 GB model so he released another statement, explaining problems with the implementation of 32 GB of memory.
Here is also an interesting article why the new MacBook Pro is limited to 16 GB of RAM.
Schiller: The MacBook Pro uses 16GB of very fast LPDDR memory, up to 2133MHz. To support 32GB of memory would require using DDR memory that is not low power and also require a different design of the logic board which might reduce space for batteries. Both factors would reduce battery life.
Apple have been using LPDDR for several generations of their notebooks, and it’s part of the way that they get very long standby time on them. Switching to DDR4 would drastically decrease it from the 30 days of standby time that they get now to less than one week. With DDR4 they’d have produced a notebook that would have a completely drained battery if it was at 50% charge and you closed the lid and left it for a few days. Not only would that be annoying, but by running the battery flat often it would end up damaging a percentage of their batteries because they’d frequently get 100% discharged, which puts a lot of stress on them, and sometimes even kills them.
