The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. It was introduced in 2007.

The Apple A5X is a 32-bit system on a chip (SoC) designed by Apple Inc. and manufactured by Samsung. Apple used it only in the third-generation iPad. The A5X is a high-performance variant of the Apple A5. Apple claimed during their media event on March 7, 2012 that the quad-core PowerVR SGX543MP4 graphics processing unit (GPU) in the A5X is two times faster than the GPU in the A5, as the A5X GPU contains two more cores than the dual-core version GPU in the A5.
