The Apple A5X is an ARM-based system-on-a-chip (SoC) designed by Apple, originally used on the third generation iPad. It was announced on March 7, 2012 and was a high performance variant of the A5 processor that powered contemporary Apple devices. It was superseded in the fourth generation iPad by the Apple A6X processor.
The A5X features a dual-core CPU at 1 GHz[3] and a quad-core PowerVR SGX543MP4 GPU clocked at 250 MHz with doubled memory subsystem (4 x 32-bit memory controllers) to provide sufficient bandwidth for the very high pixel count on the third generation iPad's Retina Display.[4]
It is manufactured on a 45 nm processes by Samsung and the RAM was not bundled together with the SoC but soldered directly to the motherboard.[5][6] The silicon die size has increased drastically compared to the A5 at 165 mm2, 3.1 times larger than the 53.3 mm2 die area of the original A4.[7]
