Ah okay, I didn't know that. So let's wait and see what the clock rate really is.

What's your estimation then on how the A6 core compares to Krait (or Cortex-A15) per clock?

Btw, I'm in good company regarding this point:
"We believe the custom A6 CPU is similar in complexity and performance to Cortex-A15 as well as to the Krait CPU that appears in Qualcomm’s newest processors. To reach Apple’s claim of a 2x performance gain over the iPhone 4S (which uses the Apple A5 processor), we expect the A6 contains two CPU cores clocking at roughly 1.2GHz. This speed is lower than what competing A15-class CPUs achieve, presumably to save power. As a result, the iPhone 5 will probably fall short of other high-end smartphones in raw CPU performance, although the same has been true of previous iPhone generations."

You're in good company then (see above) ;-)

Yeah, it seems that Geekbench favours the A6 very much, or that the A6 favours the benchmarks Geekbench consists of, depending on how you look at it. I'm surprised.
