What says Bob? > >Jouni First, Bob says 2725 has nothing to do with reality. Second, not enough data. Doubling the clock rate does _not_ double the cpu speed. Which means this is an apples and oranges discussion. I've always used the expression "doubling the cpu speed produces about 60-70 rating points." That does not mean "doubling the cpu clock speed produces ..." Just compare your favorite program on a 200mhz machine vs a 400 mhz machine. In some cases, the 400 might be > 2x faster (ie an old pentium 200/mmx compared to a PII/400 (which is based on the pentium pro core, much better processor than the original pentium core). So the clock speed isn't very interesting. The program's NPS is a better measure of speed improvement and rating increase.
