"K3PE7E700F-XGC2" the last two characters refer to the clock speed. The iPhone 4S was [under]clocked at 800 Mhz. "K3PE4E400B-XGC1" was the A5's part number. E4 refers to 2 Gb LPDDR2 die and because A5 features a dual-channel LPDDR2 memory with two 32-bit die. 2 GB x 2 = 512 mb of RAM. C1 was the clock speed which was 2.5ns which indicates a 400MHz clock frequency. Two channels result in the A5 clock speed of 800MHz.
So the A6 has C2 which is 1.9ns which indicates a 533 MHz clock frequency. 533 x 2 is ~1066 GHz*. With that said, the A6 sports a dual-core CPU with quad-core graphics and it is 2x faster than iPhone 4S's A5 CPU.
Apple new A6 processor is also using next generation ARM Cortex A15 cores, making it the first smartphone with this technology. It is also reported that the A6 shares the same SGX543 GPU (also quad-core) from the iPad 3′s A5X. But only a tear down will confirm that.
