 Actually there was a good comparison at many different levels in the (excelent)
 German magazine c't; it covered many pages (~30, IIRC):
 - In standard application benchmarks K6-III and Pentium-III are very close,
   when compared at the same clock frequency or at AMD-450 against Pentium-500.
   Mostly the Pentium was very slightly ahead.
 - Looking at software that utilizes 3D, AMD got it's winners, sometimes with a
   good distance.
 - When looking at the assembler level (mostly aiming at graphics stuff), they
   got to the result: Exactly the same (if programmed well) !
   Actually the Pentium III won when they used the new enhancement (ISSE ?), but
   you cannot expect software to use it until next year, probably :-(
 They came to the conclusion, that the iron basicallygives you the same, so
 there are to things left: pricing and the very good developer utilities Intel
 offers, AMD not.
 Still, I am just waiting to get the AMD-III at a good price and then will put
 one into my home-box :-)
 I am writing this lines from an AlphaStation though, that just beats all of
 them :-)
