Re: Will the S3 in the US Have the Same CPU?
Handset makers make the decisions they do for a reason that, to the outsider, seem weird. Why does the Galaxy Nexus have the Ti Omap which is not exactly the fastest thing in the world, losing to the Galaxy S2 with Exynos 4410 despite the S2 being the older phone?? Because Ti was chosen by Google to be the first development partner when ICS came out. A lot of people were hoping for an Exynos 4412 already in the Galaxy Nexus, but the decision was made way early in the development cycle based on what Google chose as early development partner.

What's holding the S4 back is it's GPU, the Adreno 225. It's fast, but not Adreno 325 fast. That will find it's way into the S4 Pro later this year, but unfortunately not in time to make it into the US carrier version of the GS3 (not sure on that, but from what I read, it's unlikely). I am amazed how fast the GS3's GPU is seeing how it is based on the Mali 400 that was in the GS2!
Anyways, just because you have a quad core doesn't mean it's faster than a more modern dual core, and such is the case between the Tegra 3 and the S4. The Exynos 4410 was a beast when it came out and wiped the floor with the competition, doubling it up obviously results in tremendous Tegra 3 killing speed. I am not sure how computer savy you are, but it's a good analogy. A older Intel quad core processor has a hard time keeping up with a mid to upper range dual core of the current generation. Old 60s muscle cars had huge engines, but a smaller engine today will make more power and use less fuel.
Lets see how the US version of the GS3 will fare, I am pretty optimistic based on what I saw in the AT&T version of the One X.
