    Me and my friends start testing the new X2 from ATI and comparing it with the 3870X2 and a Single 4870.

    This are the first comparisson we make comparing the frametimes between this cards, and we get surprise to see the results of the new X2.

    EDIT: We use Fraps to record Frametimes during a benchmark run, those datas where calculated using Excell to compare the time between frametimes in each card. Is that okay or need more detailed info ? I´m not the math guy ;) for that I have to ask for the guy who built the formula hehehe.

    Frametimes Explanation.
    http://www.mvps.org/directx/articles/fps_versus_frame_time.htm


    Y= Miliseconds
    X = Frame number


    Example of the data collected.

    This is DMC4 1680x1050 4xAA.

    COJ 1920x1080 4xSSAA

    The upcoming tests will be Crysis and Grid.

    And, I´m here to ask users with Nvidia SLI configurations if you can help running tests to compare the evolution in MGPU configs. If you are willing to do so, please PM me with so I can send the settings used in the test.

    Users with Single cards from NV are welcome too.

    And if any of you got any suggestions feel free to say ;)

    Before posting a bunch of graphs please example how you obtained the data to plot each dot/line

    This needs to be explained and shown. That is the heart of the graphs being shown.

    -How are you determining ms?
    -Where are the ms numbers coming from?
    -What settings are used on the card to create the results?
    -etc

    I'm a little confused as to what the numbers to the left are... I'd assume the ones on the bottom are seconds?

    Y axis = milliseconds

    X axis = frame number

    Let me sum it up for everyone: The 4870X2 line is a heck of a lot less bouncy than the 3870X2 line, which means less microstuttering. The 4870 single is shown to show what a single cards "bounciness" is supposed to be at to not notice microstutter.

    Did I explain it right? :)
