Processors: Core Duo vs. Core 2 Duo

    I am getting my Dell notebook replaced due to its repeated breakdowns.
    However, Dell says they have discontinued my model and are giving me a new
    equivalent. While both can rub Vista, I noticed that the new laptop will
    have a U7500 Core2 Duo processor running at 1.06 GHz, while the one I had
    before had a U2500 Core Duo (without "2") running at 1.2 GHz.

    Apart from the obvious difference in frequency, am I really getting an
    upgrade or a downgrade when it comes to Vista performance? What is the
    difference between Core and Core2?

    Core 2 Duo is a very nice upgrade over the Core Duo CPU, even at a loss
    of .2 Ghz, the Core 2 Duo chip will be a better/faster CPU for all of
    your apps.

    You can search the Intel website for the details.

    Thank you for the kind response. I have already tried to find the answer a
    Intel's site, but could not find it. I could see generic descriptions of
    both chip families and a lot of information about their functionalities, but
    no way, direct or indirect, to compare performance in any meaningful manner.
    That's why I decided to post the question here.

    If the Core 2 Duo is better/faster even though the clock frequency is lower,
    why is that? What is the feature that makes it possible? And in what
    measure? As an example, I would like a statement that one chip can perform
    x% more calculations in the same time, or something to that effect.

    You won't get a specific statement.

    The difference is in how the chips were designed, how they perform the
    same tasks - one chip is more efficient at doing more things in the same
    time as the other.

    There is no way that you're going to find a definitive x% faster
    anywhere, it's not just possible as there are many factory that impact
    that number.

    Anyone that has systems with Core Duo and Core 2 Duo and Quad Core 2
    systems will tell you that the same speed CPU ranting is faster as you
    go from Core Duo >> Core 2 Duo >> Quad Core 2... Even XP benefits from
    this progression, but the real benefit is when doing more than one thing
    at a time.

    That's exactly what I've been looking for!
    Thanks a million!

    The article does not give what you asked, it only shows the technical
    differences, not how much faster one is over the other.

    The Core CPU is a 32 bit CPU and the Core 2 is a 64 bit CPU.
