Not really. The Pentium M is apparently based on the P3 but they're really very different. The Inquirer had a good article about the differences but I can't find it right now. If you look at Intel's slides, e.g., http://www.anandtech.com/mobile/showdoc.html?i=1800&p=3 you can see that they're different. The P3 didn't have "Micro-Ops Fusion," "Dedicated Stack Management," SSE2, or a 400MHz bus. The Pentium M reportedly has a longer pipeline than the P3 and a better branch predictor. -Tom
