The A6 processor in the iPhone 5 was on the sensitive plate placed with an electron microscope. The soc seems to be three gpu cores and produced by Samsung, not TSMC as the rumors suggest.

The photo was taken by ubmtechinsights and reveals, among other three gpu cores and two lpddr2 memory channels of 32bit. There was all the necessary speculation as to the gpu, which has the same performance as the PowerVR SGX 543MP4 in the A5X soc, which in the latest iPad. The photo, however, shows that there are three nuclei are present, which, according to Anandtech a clock speed of 266MHz. The size of the chip is estimated to 95mm2, a lot smaller than the 122mm2 of the A5 soc in the iPhone 4S. The ARM-cores, which Apple themselves were developed to do their work at a clock speed ranging from 800MHz to 1200MHz.

The chip is smaller, among others, by the use of Samsung’s 32nm-process, while the A5 and the A5X is still on 45nm were fried. Also, there are only two 32bit memory channels present, good for a 64bit memory bus compared to the 128bit memory bus for the A5X soc. This is possible because the iPhone 5 has a much lower resolution than the new iPad, and therefore less memory bandwidth needs. Another photo of ubmtechinsights shows that Samsung is the production most likely.
