880 is 3,33ghz (2 speedbins )

And if you look at Singelthreaded scores, the increase in performance is quite respectable... a 3,1ghz cpu beats a 3,73ghz cpu (ST)? Or in MT apps a 3,1ghz cpu beats a 3,33ghz cpu, and most of the time we are in the double digit range...

So offering more performance then a 880 and consuming 20% less energy while doing it.
