i guess its more of a question about lack of hardware.. i came from a droid. on good days i got away with clocking it to 1.2g. i understand it has a separate graphics processor or GPU. i have no idea what that is or the benefits of having one. as an example i ran the psx emaulator (gran turismo) on my droid and the video was choppy at best. now im using my droid x and the video is seamless. im wondering how a GPU functions and why or why isnt there a benefit to having one? on the base level i was running a higher clocked processor with aGPU and things were slower than my non GPU droid x. as i typed that i also had an idea; since i used custom kernels on my droid (and dont have that option on my x ....) perhaps the lower voltage slowed down the graphics on my droid? i dunno im just poking around online about anything to do with overclocking hte x and this question arose.
