That is the answer: pipelines on the Intel CPU are more numerous but have a higher resistance becasue of the physical channel size in relation to the registers vs proximity and resistance (which is less, in both cases in AMD chips). A 2.2 gig AMD does, infact, translate to 3.5 Ghz P4. If you notice, all of the newer cpu's are adding cores and pipes and reducing the core clock speeds. The Conroe is a perfect example.
