A lot of people seem confused about MHz gaps between IBM's PowerPC 970 chip and Intel and AMD's 64-bit chips. Well, the truth is, there is no gap. Here is proof:

I could not find information on the clock speeds of AMD's future Hammer processors, but if anyone else can please post them here.
Bottom line is, there is difference in the overall performance of 64-bit chips vs. 32-bit chips; 64-bit are faster in overall performance than 32-bit chips.
Hope this helps. If anyone on MacRumors can better explain things, please do. Thanks.
