"The thing you have to remember is that this was before the iPhone was introduced and no one knew what the iPhone would do ... At the end of the day, there was a chip that they were interested in that they wanted to pay a certain price for and not a nickel more and that price was below our forecasted cost. I couldn't see it. It wasn't one of these things you can make up on volume. And in hindsight, the forecasted cost was wrong and the volume was 100x what anyone thought."

iPhone 5 A6 CPU has dynamic Clocking

I just installed Geekbench 2 on my iPhone 5 and it showed a clock speed of 1.10Ghz (see photo above). The first Geekbench we saw before the official launch had 1.02Ghz. Now more reports come in that show different A6 CPU clockspeeds. Speeds seen vary from 550Mhz to 1.3Ghz. With dynamic clocking Apple can save power and offer increased performance when needed. Another little thing that helps make the iPhone 5 the fastest smartphone on the market.

It has also been discovered that Apple went the extra mile and laid out the A6 Core by hand. This can help efficiency and speed compared to an automated process.
