Apple A5 Information

The Apple A5 is a package on package (PoP) system-on-a-chip (SoC) designed by Apple and manufactured by Samsung[1] to replace the Apple A4. The chip commercially debuted with the release of Apple's iPad 2 tablet, and also powers the iPhone 4S. (This is consistent with how Apple debuted the A4 chip: first in the original iPad, followed by the iPhone 4, and then the iPod touch 4th generation.[2])

The A5 contains a rendition of a chip based upon the dual-core ARM Cortex-A9 MPCore CPU[3] with NEON SIMD accelerator and a dual core PowerVR SGX543MP2 GPU.[4] Apple lists the A5 to be clocked at 1 GHz on the iPad 2's technical specifications page,[5] though it can dynamically adjust its frequency to save battery life.[6][3] Among the customizations that Apple has done to the chip is including an image signal processor unit (ISP) that will do advanced image post-processing such as face detection, white balance and automatic image stabilization.[7]

Apple states that the CPU is twice as powerful and the GPU up to seven times as powerful as its predecessor, the Apple A4. The A5 package contains 512 MB of low-power DDR2 RAM clocked at 533 MHz.[8][9][10][11] The A5 is estimated to cost 75% more than its predecessor; the price difference is expected to diminish as production increases.[12]
