This looks like an upgrade of the already most awesome phone in the world, they increased the screen size from 4.3" to 4.5" and they increased the processor speed to 1.5Ghz Dual-core. I am just speculating here, but this processor might be the Texas Instruments OMAP4460 at 1.5Ghz, or perhaps it is a new version of the Samsung Exynos clocked at a higher clock speed. Perhaps this processor does improve video playback and 3D performance. If you have any information about the processor used in this device, please post in the comments. This might be pretty close to the hardware that may be used for the Nexus Prime, Ice Cream Sandwich reference development platform.
