Oops,
I forgot to say that the above numbers are from a list maintained at our
institute. The official WWW page of the SPEC organization is located at
URL = <http://www.specbench.org>.
Moreover, our list contains the following numbers for IBM/Motoral PowerPC:
PowerPC 604e 300MHz ~13 SPECint95
350MHz ~15 SPECint95
PPc G3 740/50 266MHz ~12 SPECint95
300MHz ~13 SPECint95
