Me thinks the 6+ is definitely CPU/GPU restrained, and the a8 (and the 64 bit a7 before that) is the secret sauce. Also remember that it's not specs, but integration into the target OS as well. Touch Response (no 'Laggies' ) is critical. I think it's less about the screens, and more about moving the larger number of pixels around as fast as your fingers can move.
