    I am trying to decide what laptop to buy, and was wondering if there is a difference and if there is, how much, between AMD mobile sempron and Intel moble Celeron processers.

    If you take Sempron vs Celeron, Sempron has power saving feaures and it is low-power at 25 watts. For same battery capacity Sempron should give more battery life.

    But I also think Mobile Celeron is very good for the price we pay.( much more value than P-M), it is as good as 400FSB P-Ms with 1MB cache.

    Is there some Benchmark that gives battery life based of different processors?

    No sorry, but you could always use NHC (Notebook Hardware Control) and lower your CPU's voltage to get better battery life.

    So are people in concurance that the sempron gives a better battery life, or is this just one person's opinion?

    I'd say in general, Centrino wins over battery life and efficiency

    This ain't Centrino we're talking about. This is the Celeron-M versus the Mobile Sempron, not just the Pentium-M versus the Turion. In the Pentium-M case, the Pentium-M would totally kill the Turion in terms of battery life, but most people aren't sure about Celeron vs. Sempron, as most people here have higher end processor. We can't count on the Sempron having an advantage over the Celeron just because it has more power saving features, as the Turion MT had a 25W TDP and the Pentium M had a 27W TDP, and the P-M still killed the Turion.

    Nope, you can not use NHC or RMClock to reduce voltage for Celeron. This has been researched enough and has been posted here before several times.

    Sempron can be Undervolted, but it seems new semprons have limitation for lowest stepping voltage( at 4x), but other stepping you can undervolt fine.

    I am sorry, and tired of heating this myth again and again. Please read the clash and Titans( laptop logic article again) , that too with ML series processor, not with MT series. I have used both P-M and Turion ML laptops and sofar my experience proved it is a myth. Both are pretty much on par with each other in battery life. There may be differences in battery, other hardware which may be causing differences, and also some people had problems with AMD processor driver on Turion laptops which causes the CPU run at Max speed always( causing less battery life).

    Please let us know if you had different experience with all the facts.
