How come Apple claims the SSDs are 50% faster in the new release?

    Maybe this is a Kaby Lake thing? I'm contemplating getting either the new or a used late 2016 model. Aside from the processor bump the only two things that catch my attention are:

    1) They claim SSDs are 50% faster
    2) Maybe 32GB RAM will be faster in Kaby Lake....?

    I am not a very savy person so please correct me if I'm wrong. It appears all else is the same?

    I think the ssd speed increase has to do with the connection between the ssd, motherboard controller, and CPU.

    They were referring to the Macbook, or at least this is what is written on the Apple's website. I think the 2016 and 2017 MBP have the same SSD that is incredibly fast.

    About the 50% faster SSD, I think they were talking about the ones in macbook, not macbook pro.

    Thanks for helping me understand this everyone! Does anyone have an opinion on whether Kaby Lake will have a better shot at getting 32GB RAM in an update?

    I'm wondering if I'm better of getting the new one or an old one. My needs are more about GPU than CPU so as long as I get 4GB I should be good --- unless you all think the updated GPUs are that much better.

    Not possible for 32GB of RAM until Coffee/Cannon lake. Well not possible without sacrificing battery life which Apple doesn't want to do. I don't want them to either.

    If you work with a lot of 4k material, definitely purchase the new with Kaby (if nothing else, your battery life will likely be much better over a Skylake model when working with 4k.) If you do not, there should not be a very big difference in regard to the 15-inch models. If you are highly GPU-dependent, both the 2016 and 2017 models have Thunderbolt 3 and the potential future of using external GPUs (since internal laptop GPUs are generally very weak compared to desktop counterparts.)

    In regards to SSD performance, sometime in the next year performance of both of the 2016 and 2017 (and pre-2016) models may actually increase significantly, but this will be as an outcome of a new file system that will replace the current (archaic) one.

    Thanks, I am buying this for 4K purposes so your input is appreciated. Think I'll stick with the latest.

    If you are using 4k, the premium for the most current Kaby Lake is definitely worth the pricing IMO.

    If you need 32-64GB of RAM for usage, there are some pretty nice desktop offerings from Apple that were just announced.

    The most important of SSD is not the sequence speed, is the type (MLC/TLC, 3D/2D) and the process "nm" of NAND
    people rarely need transfer large GB file to save few seconds (For very large transfer, It will overheat)

    Instead, people require low latency, good concurrent write/read, and withstand stable and good reliability.

    On those years, the sequence speed may improve faster due to parallel read write (however will overheat),
    but the latency reduced due to process become small, block size and page size increase and require more complex ECC for solve the smallest chip (lower endurance) effect.

    So, Apple claim the SSD speed huge improve but definitely not so much improve in real life after 2013 ...
