I'm guessing all touch devices Will have either 1 or 1.2ghz and non touch devices will have 800 MHz.
Most likely it is due to that other one being in the Curve family that is the reason for the slower processor and all the higher end brands will get the same 1.2ghz processor simply because it will be most cost effective to do it that way.
