http://forum.xda-developers.com – The Galaxy S III has been outclassed in the performance department by the iPhone 5. Everything is faster on it with the new Cortex-A15 processor by it. I am not sure how the international GS3 does against it overclocked. But it's probably safe to say the new iPhone is the most powerful LTE device on the market at this moment. Although it's nice likely, it would be nice of the Galaxy S IV used the Exynos 5450. The iPhone's hardware improvements alone won't make me switch because it's still an iPhone that runs iOS but I hope Samsung turns up the heat in response. (HowTos)
