    There is no such thing:

    Imagine a sustem with 100 Tflops. and other with 75 Tflops... The diference is 25%!

    To calculate the percentage increase:

    First: work out the difference (increase) between the two numbers you are comparing.

    Increase = New Number - Original Number

    Increase = 100 - 75 = 25

    Then: divide the increase by the original number and multiply the answer by 100.

    % increase = Increase ÷ Original Number × 100.

    % increase = 25 ÷ 100 × 100. = 25

    If your answer is a negative number, then this is a percentage decrease.

    So lets change the order:

    Increase = New Number - Original Number

    Increase = 75 - 100 = .25

    % increase = Increase ÷ Original Number × 100.

    % increase = -25 ÷ 100 × 100. = -25

    So there is a decrease of 25%...

    That 33%, is the percentage over 75 that would be required to reach 100. That's 25 units or 33,333(3)% of 75.

    By your calculations, PS5 and Xbox séries X would have 15,3% and 18,09% if we calculated decrease or increase (two values for basicaly the same thing)... But in reality the number is one and one only: 18.09%. diference either in increase or decrease.

    its very easy to me and you don't have to explain to me ;d but it just better to use percentage as "that would be required to reach" as In first approch of one is 100tf other 50tf and you say its 50% difference when one card has 2x power so 100% faster (and not 1.5x as some could interpret that 50% difference)

    If consoles X finishes a frame in 30 ms and console P the same frame in 20 ms:
    -console X is 50% slower than console P (takes 3/2 as long as P)
    -console P is 33% faster than console X (takes 2/3 as long as X)

    If you want to emphasise that P is faster than X you'll say that X is 50% slower than P.
    If you want to emphasise that X isn't much slower than P you'll say P is 33% faster than X.

    Both are correct, and the one you use depends on what you want to emphasise.

    This has always been the correct answer. And I've tried to explain it that all the formulas work, but the emphasis is just the perspective one wants to tell.

    No, doing something twice as fast takes half the time. 10% faster implies a ~9.1% reduction in time to completion.
