    How reliable are tests with one and only one computer?

    Normally, for statistically reliable results, you need between 18 (low side) and 20 (somewhat better) devices to use for comparisions.

    Then you could say that you have consistant results with a 5% confidence interval.

    Each laptop will have variances in components. Even the clock speeds may vary slightly, as would logic switching speeds. These would allow some laptops to favor some results and not others.

    Therefore, you should take the Phoronix results as measure of results based on a single machine but not as a measure of a batch of machines, or as other than driver differences executing on that specific machine.
