Is a pentium m 2 ghz 760 = to a pentium 4 3.8 ghz?

When running a 3.06 Pentium 4 with HT Technology as your desktop (plugged into an AC adaptor) I guess it is ok, but otherwise using it as a laptop would be less than advantageous. In terms of #s how long would a Centrino battery run as compared to the hour or so the P4 gets?

In almost all cases a lot longer. My notebook has a dedicated GPU that uses extra juice and a 15.4 in widescreen. I get between 1.75 and 3 hours out of a 6 cell, depending on what I'm doing. There are smaller display units with the intergrated intel graphics solutions out there that get up to 5 hours out of a similar battery. Also, I have a Sonoma version of P-M; the earlier version, the Dothan, has better battery life and runs cooler... it is also a marginally lower performance chip largely due to it's slower bus speed. A number of people think the Dothan is the best of the 3 major P-M varients (the last, or actually first, varient is the Banias). There are other ultra-low wattage sub-varients but you won't find them in common usage. To add to the confusion there are two different chip set platforms and 3 different wireless cards.

the 650 3.4 ghz pentium 4 has a 2mb L2 cache, and the m 2 ghz has a 2mb of cache. I have looked at the different core components and spaces of the chips and they look very different, so i was wondering how these two processors differ in terms of cache and how that cache will help. The m has a much bigger area for cache and the 4 650 (64 bit) has a much more complex core.

Would the pentium m 2 ghz be equal to a pentium 3.4 hyper threading? i did some calculations - 2x2 = 4 with out hyperthreading, and then subtract 600 mhz and u get a 3.4. Are these numbers fair and accurate.

on that link the non ht 3.6 outperformed the 3 ht for some benchmarks, and did the opposite for other benchmarks. Would the m vs the 4 ht have the same results. So does the ht really make a difference?

The comp i would buy is the dell precision m70 workstation with 2 ghz pentium m, 1 gig of ram, and a 7200 60 gig hd.

thanks again...
