Why are all 15-inch processors i7?

    Are all quad-core processors i7 by default? Are there no Haswell quad-core i5 processors? Not that it's a bad thing, but just something I noticed.

    Took me by surprise as I figured there would be a i5 > i7 upgrade path on the 15-inch model. Does this mean the difference between the 2.0 CPU and the 2.6 are minimal?

    I know the differences between the i5 and i7 on the 13-inch, but if all of the 15" processors are i7, would it have any differences aside from clock speed? Such as more cache/turbo boosting for iGPU? And can we assume battery life would be nearly the same across all of the i7 processors?

    To get a quad core, you have to have to go with an i7. Apple chose to go with processors that all feature Iris Pro graphics, so they really only had 4 i7s to choose from and the 4950HQ wasn't a big enough jump from the 4850HQ.
