Apple's A5 Chip Examined Under a Microscope

By Wesley Fenlon

The A5 has been given the electron microscope treatment. Take a look!

Curious what Apple’s A5 processor looks like? The brain behind the iPad 2 and the upcoming iPhone 5, the A5 system-on-a-chip combines a dual-core processor and PowerVR GPU to deliver improved performance over the 2010 model. Chipworks disassembled an iPad and put the A5 under a microscope to eyeball all of the changes between the two Apple processors. With its dual-core ARM Cortex-A9 processor, the A5 is more than double the size of its predecessor, measuring 10.1mm x 12.1mm compared to the A4’s 7.3mm x 7.3mm.
