So can these Phenom II clock their cores independently or not?
This could be a very good thing, we could have 2 higher-clocked cores for "hard work" and 2 lower-clocked cores for backup. This way we could allow higher clocks\less heat\less consumption for the CPU and have a boost on single\dual-threaded applications.

Better that this is only having Cool'n'Quiet working independently for each core.
