|The name of the game is called “unlocking the multiplier”, which will be played with the SB700 and SB750 southbridge chips. If you are running an upcoming 2.8 GHz Black Edition CPU, a motherboard with the old SB600 model (RD690) will keep the processor cores operating at 2.8 GHz. However, if you have a motherboard with the SB700 chipset, you will receive a free upgrade to 3.0 GHz. And if you get a motherboard with a SB750 chip, your processor will run at 3.2 GHz, which matches the clock speed of the Athlon X2 6400+ - the highest clocked processor AMD ever offerred.|
This was rumored before on Fudzilla, but this has more of an explanation of how it works.
