    [8]What is the difference between, for example, a 3.06GHz P4 or an equivalent speed in an M or Centrino processor? Which runs faster and which types of applications run best on each? I'd like to have a power notebook for gaming with a great video card and a dual format DVD-R/RW /DVD-ROM setup. All replies welcomed.

    this question is asked a lot. here's another message thread where Andrew has answered the question of Pentium M speed versus P4 speed:

    I think it's worth saying the power consumption and thermal specifications of these processors as well:

    Pentium 4 - 115 - 81 Watts (Depends on frequency) @ 70C
    Mobile Pentium 4 - 70 Watts @ 100C
    Mobile Pentium 4 M - 35 Watts @ 100C
    Pentium M - 21 Watts @ 100C
    Celeron - 35 Watts @ 100C
    AMD Athlon 64 low power (2800+ and 2700+) - 35 Watts
    AMD Athlon 64 (2800+, 3000+, 3200+) - 62 Watts

    Note: I didn't find the thermal specs of AMD, but if I do I will post it.

    [8]Thanks to everyone for your prompt replies. Which model(s) should I choose? How about the Sony K-17, for example? It has been discontinued but it really packs alot for the punch. Here's a link to it:

    If you are using it for gaming, the first thing you should be thinking about is the video card. That vaio uses shared memory, a big no-no for serious gamers. You probably want 64 megs of video RAM and a radeon 9600 or better chipset, for speedy DX9 compatibility. Spend your money on a good video card, and get the cheapest Prescott you can find. This will let you upgrade later, as desktop chips are easier to find than mobile chips. When your book is getting slow, you can pop in a 4 ghz prescott or something.
    As for pentium M versus Pentium 4, you might want to see this: http://translate.google.com/translate?hl=en&sl=fr&u=http://www.x86-secret.com/articles/cpu/dothan/dothan-7.htm&prev=/search%3Fq%3Doverclock%2Bdothan%26hl%3Den%26lr%3D%26ie%3DUTF-8%26sa%3DG
    It says that a pentium M at 2.4 ghz (that is overclocked, they don't get that fast) competes with a 3.4ghz pentium 4 EE. A pentium M 755 would be equivalent to a 2.8 ghz pentium 4 EE. The Extreme edition is the critical part, the cache sizes alter the results. The reason multiplying by 1.5 or whatever doesn't work is because the cache sizes are different, so they are not comparable in terms of clock rate.
