I'm replying to you, talking about people that don't read the forums. You said that "most people know it's 4+4", I don't think 'most people' do, hence my clarification.
No I didn't, I said....
"The vast majority of apps will work better on a higher clocked quad core (like the snappie) than a lower cloked 'octo' -core (like the Exynos)."
and tried to further explain that notion further by also saying in another post that...
"A single threaded application will run better on a 3GHz single core processor than it will on a dual core 1.5Ghz CPU."
The first is directly about the two CPUs to be used in the S4, the second is an example on the same subject but using a different scenario.
The salient piece of information you seem to be missing is that the four cores of the Exynos are clocked at 1.6GHz, the four cores on the snapdragon are clocked at 1.9GHz. So the snappie would be faster with any application that isn't optimised to use more than four cores (which is pretty much all of them).
Fair comment but this whole battery saving thing is an assumption right now. As far as I'm aware there are no benchmarks or much information for it so anything on battery savings is speculation at the present.
But it does mean you shouldn't put off buying the phone or choosing another out of spite cause you wanted the octocore (which is some of the replies my original comment was aimed at).
