That's like saying the Pixel 1 should be able to do what the Pixel 2 can, even though it lacks the Pixel core processor. Apple added extra cores, and an overall more modern framework to their processors to essentially do the same thing.
I am sure it may have worked on the X, but it likely would have been much slower with less "keepers".
Come On ... The X is one year old ... before one year it was apple greatest product ever. This foto comparison shows only how inferior apple worked on the X. The X has every power in the world for the Xs features.
You people really scare me, when I read all this unfiltered praise for a product, which is just one year away from its predecessor and they just adjusted the lightning a bit.
The sign is on one foto dark on the other light brown - both shot with an iphone - if such things happen you should question if apple is still sane. I mean we had cameras years ago which could take more color truth fotos
