So 3Ghz Phenom vs 3Ghz PhenomII would mean no clock increase with shink at start.
It's a general rule of thumb in the industry. Moving to a new process brings you two advantages :
-die size reduction, maximum is 50% (0.7*0.7 )
-20% more frequency for the same power

All new processes ussually claim 20-50% power reduction or alternatively 20-40% more clocks for the same power consumption.
