Petz <I see no differentiation between the Pentium III and the Pentium II.> Unfortunately, there is a technical difference. They followed AMD in going to C4 layout, plus added extra interconnect layer, ( = reduced die size and interconnect delays). They increased superpipelining at least in area of tag comparators ("domino tags"), tweaked the process to get it into 1.8V. All this will result in higher frequency ceiling. Overall performance on regular x86 code will remain obviously the same (per MHz), but all these improvements together add a serious life to the aging Pentium-Pro design. The tough times are still ahead for AMD.
