Apple Insider posted a story that Apple's next-generation iPhone will be powered by a quad-core ARM processor based on Samsung's Exynos 4 architecture, according to a new report.

Last year's iPhone 4S features a custom dual-core processor clocked at 800 megahertz, dubbed by Apple the "A5." That chip was first introduced months earlier in the iPad 2, where it ran slightly faster at 1 gigahertz thanks to a larger form factor with a bigger battery.

With the third-generation iPad launched this year, Apple didn't unveil a true next-generation chip, choosing instead to name the processor the "A5X," suggesting an evolutionary upgrade over its predecessor. That CPU is based around Samsung's 45-nanometer low-power architecture, also found in the A5 CPU in the iPhone 4S and iPad 2.
