Reasons to believe K7 is faster than PII core: eetimes.com "While Katmai remains a relatively stock Pentium II design with an extended SIMD unit, the K7 is a ground-up re-architecting of the IA-32 instruction set. With three general-execution units and three address-calculation units, K7 will be “a wider superscalar machine than the Pentium II,” said AMD's director of K7 engineering, Dirk Meyer. On the floating-point side, particularly for X87 code, the difference between the K7 and the Pentium II “is even more apparent,” he said. The K7 has two double-precision, fully pipelined X87 data paths, compared with one for the Pentium II — which, according to Meyer, is not fully pipelined for double precision. “If you want to do an X87 instruction on the Pentium II, in one sense you cycle the instruction through the pipe twice. So in some ways, for double-precision X87, the K7 has four times the peak execution rate.”"
