Most programs run faster on the P II chip. But most chess programs run faster on AMD, but not all. I have asked many time why this is so. One programmer told me it was due to the code and how it was compiled. I think Bob has said his program runs best on the intel chip. >At the moment AMD by far is simply the best processor around. > >But the Intel (slot-2) is coming, will it out-perform AMD? > >Maybe, but certainly not in price.
