Re: Confusing much?
Just seeing lots of people going "but it's the same chip across all of them" as if Intel's chips of a certain generation aren't all pretty much exactly the same.
Intel don't make 5 different i7s or whatever, they make one, bin it and then lock the frequency to create artificial models at different price points.
People fall for branding that Intel and AMD use as we're so used to CPUs being sold to us in that way.
The way I see it, Apple have no need to do that with their own chips. Instead they'll adjust the TDP and power envelope to suit the device at hand and maybe use chips with failed components in lower ranges. (Like the air with only 7 graphics cores)
