Apple's A5X SoC: Quad-Core Graphicsby Anand Lal Shimpi on March 7, 2012 1:25 PM EST
Apple just confirmed the new iPad uses an Apple A5X SoC. Its main improvement? What Apple is calling quad-core graphics. Our guess? Dual-core Cortex A9 plus a PowerVR SGX543MP4, an upgrade over the 543MP2 used in the iPad 2. Clock speeds are still unknown, however Apple is claiming 2x the performance over the iPad 2 implying equal GPU clocks.
It's also very interesting that Apple used NVIDIA as a baseline for GPU performance comparison, boasting 4x the performance of the Tegra 3.
