Re: "So the Pentium III will need KNI to come close to the K7."

It seems pretty clear that AMD's response to KNI is to create a super-FPU on the K7 which will hold off Intel until AMD can implement its own version of KNI, if AMD decides it's necessary.

The question is, will AMD need it? A K6 with 3DNow nets a big performance increase over a K6 without 3DNow. But will a core like the PII, which already has a good FPU, show the same kind of dramatic improvement drawing on KNI SIMD? Or, to ask the question another way (these numbers are just made up), if the vanilla K6 gets 20 FPS in Quake 2, and the K6-2 (w/3DNow) gets 40 FPS, then if we had a hypothetical K6 with a pipelined FPU that got 40 FPS without 3DNow, would a 3DNow version of that hypothetical pipelined K6 get 80 FPS? 60 FPS? 50 FPS? Less?
