the reason from what I understand between amd, and the pentium for the speed difference...
it kinda goes like this...(this is very basic)
on the 64 bit processors amd processes 2 32bit commands per cycle, and the pentium processes 1 64bit command per cycle.... thus with video commands which tend to be shorter... the amd can basically process 2 commands per cycle, and the pentium only does 1... however with many database type commands...(buisiness stuff) the amd doesn't perform quite aswell as the pentium because it has to break the larger commands and data apart more often since it only can handle 32bits, where the pentium is less likely to have to break it apart...
anyways... when I refer to command, I am refering to any commands and any data that goes along with it...
so that's why amd makes it's claim.... at processes a shorter data set, but it does it on the upside and downside of the cycle... achieving about 1.5 times as many commands on average overall.... in the same number of cycles
I am not an expert in this, but this is how it was explained to me....
