Centrino (Pentium M) - What do the differnt Centrino processor speeds equate to in regular processor terms?

I got this from CSmith06's sig. Seems about right to me. Not sure what above 1.7 would be. I'm guessing a 2Ghz would be about 3. Just a guess. Maybe higher. The higher cache is great.

P-M Processos and their approximate P4 Equivalents
P-M---------------------P4
1.70 GHz-------------2.72
1.60 GHz-------------2.56
1.50 GHz-------------2.4
1.40 GHz-------------2.24
1.30 GHz-------------2.08
1.20 GHz-------------1.92
1.10 GHz-------------1.76
1 GHz-----------------1.6
900 MHz--------------1.44

Someone just told me it is roughly equivalaent to taking the M Processor speed and multiplying it by 1.6.  So taking the M Processor of 1.5GHz x 1.6 = 2.4GHz in regular processor speed terms.  If anyone thinks this is incorrect, please let me know.

Yes, this seems to be correct if with regular processor you mean a Pentium 4. For example the fastest AMD Athlon64 that are as fast as a P4-3.4Ghz or more run at a real clock frequency of little over 2 Ghz.

On the other hand, Pentium-M 1.5 == Pentium4 2.2 to 2.4 is only an approximate estimation, because they use different architectures.
For example there are programs where the P-M 1.5 runs like a P4 2.0, in other applications it can easily beat a P4 2.5.
