The Apple A5 is a package on package (PoP) system-on-a-chip (SoC) designed by Apple and manufactured by Samsung 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.)

The A5 contains a rendition of a chip based upon the dual-core ARM Cortex-A9 MPCore CPU with NEON SIMD accelerator and a dual core PowerVR SGX543MP2 GPU. Apple lists the A5 to be clocked at 1 GHz on the iPad 2's technical specifications page, though it can dynamically adjust its frequency to save battery life. 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.

Apple states that the CPU is twice as powerful See Less
