JC, I'm basing my assumption on the notion that the 10-stage K7 pipeline is already very well-balanced. That suggests that there isn't much to gain by taking the K7 pipeline and increasing it by a couple of stages. <For all we know, the Pentium 4 may not be ramping as high as a classical 20 stage processor normally wood. This was one of Scumbria's sore points about the P4, if I accurately recall it.> Yep, this is exactly what Scumbria said. He blamed the 2x integer execution unit. Tenchusatsu

>The K7 is going within between 20% and 30% of the P4 clock speed. Paul DeMone has an interesting argument for why P4 will ramp better on smaller process technologies compared to the Athlon. He states that the P4 includes in some areas wire delays as stages. This may be an advantage for Intel; however, if this is not the case, then there is not too much reason to assume that the K7 family will not be able to remain within 30% of the P4 successors.< You are forgetting that Intel is moving to copper at 0.13-microns. If K7 is within 20% of P4's clock rate with copper versus aluminum, and copper provides a 20% boost, K7 will only be within 30% @ 0.13-microns without SOI. This figure drops to about 40% @ 0.13-microns if the current figure is within 30%. The question is, will AMD gain as much from SOI as Intel does from copper?
