iOS 4.3 shows iPhone 5 using same A5 as iPad 2
An early look at the publicly released iOS 4.3 update has confirmed that the iPhone 5 will be getting the same A5 chip as in the iPad 2. Both the tablet and the future iPhone, codenamed the N94AP, are listed as using the same S5L8940 processor. They don't confirm the clock speed, but Apple ran a slightly underclocked version of the A4 in the iPhone 4.
The switch would give the iPhone its first dual-core processor and should at least make it competitive with a slew of Android phones, including the Motorola Atrix and LG Optimus 3D. It would guarantee support for 1080p video output, broader multitasking and other tasks that are difficult or impossible with current single-core processors.
The A5 consumes roughly as much power as the A4 and should have PowerVR SGX543 video. It's not yet known if it's running the contemporary ARM Cortex-A9 architecture used in the NVIDIA Tegra 2 or TI OMAP 4430, or else if it's just using dual Cortex-A8 parts. It's constructed on a 40 nanometer process and assembled by TSMC.
Apple is presumed by most to be unveiling the iPhone 5 in June at WWDC with a launch either that month or in July. [via 9to5]
