Apple Insider posted a story that a closer look at Apple's new A6 processor found in the iPhone 5 has found that the system-on-a-chip includes two CPU cores, three graphics processing units, and a full gigabyte of RAM.
The teardown of the A6 chip was conducted via a collaboration between Chipworks and iFixit. They used an ion blaster to remove layers of silicon and find out exactly what's inside Apple's custom-made chip.Teardown of Apple's A6 processor finds 1GB RAM with 2 CPU & 3 GPU cores
Under a microscope, they found that the device has a gigabyte of Elpida LP DDR2 SDRAM. That same RAM is also used in the recently released Motorola Droid Razr Maxx.
