As I said, we were talking about "standard" cpu's.
I was not aware of any 1.8Ghz cpu from motorola, though IBM's 970 runs or at least is suppost to run at that speed.
You are quite right, its not all about speed, even in the PC market its not, though intel will have you believe otherwise.For the desktop is more about the video card...a fact I was made painfull aware of when I bought my first voodoo2( a wonderful card)
Not only did it increase my fps from around 10-60+, the graphics were hugely clearer, had more detail and ran at much higher resolution.(battlezone is the case in point here)
In any case, for the server style or laptop market, a cpu with a power advantage has a good case, its up to the marketing department to push it and make the sell.
In a realist point of view, it is quite difficult to say "this cpu beats that" and you will often find that like in all things, one way works for some, and another for others.
