I would hope that the Pentium III would have multiple integer units, it does do out of order execution so it wouldn't be that difficult to make it superscalar. But i've searched through the Intel site for about an hour, and i still cannot find anything saying that the Pentium III is superscaler.
I thought that Intel and AMD were somewhat close, and the clock speed was the major difference, but but then i went to http://www.amd.com/products/cpg/athlon/techdocs/pd f/22054.pdf and also to http://developer.intel.com/design/pentiumiii/datas hts/244452.htm Athlon is a superscaler processor that is capable of issuing 9 instructions per cycle, the Pentium 3 according to the intel document is not superscaler, it can only issue 1 instruction per clock. so, what does that mean? Thoeretically the Athlon can do nine times more instructions per clock cycle than the pentium 3!! It probably will not actually issue 9 instructions per cycle because of data dependencies between instructions, but it will definatly be able to issue more than one on average! i have lost all faith in Intel tonight...:(
