    The only thing to take away from the pi fast benchmark, is how quick a cpu is at running pi fast. Literally, that is it. I don't see any correlation from running pi fast, to running any other particular game or software. If I want to know how well a cpu performs running something, I'll search out specific benchmarks similar to the conditions I'll be running with (cpu / gpu and other hardware).

    Is pi fast a good indicator of single threaded cpu performance? As a legacy test, perhaps. I have no idea what extensions it uses, so it may well be biased towards one particular set of cpus, which looking at this thread it most definitely is. I wouldn't think my 7 year old Intel i7-2600k is better than the AMD R7 1800X, not even remotely.

    I have no idea - 3.14159 is more than accurate enough for my every day requirement, I don’t need to calculate it to any higher degree of precision.

    Kinda pleased with the old girl - i3770k not overclocked, running at 3000MHz, 16Gb DDR3 at 933Mhz.
    Series computing 16.39
    division: 1.47
    InvSqrt: 0.94
    Final huge multiplication time : 0.61

    Total computation time : 16.39 seconds

    Duration : 15.60 seconds

    i7-7700k (4.20GHz) in a Clevo laptop chassis

    I notice the test gets results roughly 5 secs slower if I run the .bat with Chrome open

    16:08 Seconds - i7 2700k @ 4.7GHz / 16GB 1600MHz RAM

    Series Computing Time 13:07
    Division Time 1:46
    InvSqrt Time 0:90
    Final Huge Multiplication Time 0.61
    Total Computation Time 16:08

    Still waiting for a valid reason to upgrade this CPU as it still does everything i need it to which is primarily gaming at 1440p with a GTX1070 and a bit of photo processing.

    Doesn't look right to me, your series computing time should be less than the total computation time, and certainly not the same.

    Re: QOTW: What do you score in Pifast?

    so, i7-870 at stock with RAM running at default (so presumably only 1600Mhz), and with meltdown patches running,

    Series computing time : 20.34
    Division time : 2.12
    InvSqrt time : 1.34
    Final huge multiplication time : 0.89
    ---------------------------------------------------------------
    Total computation time : 24.76 seconds(~ 0.01 hours)
    Writing informations into file pi.txt

    edit, and this with meltdown disabled:
    Series computing time : 20.33
    Division time : 2.11
    InvSqrt time : 1.34
    Final huge multiplication time : 0.87
    ---------------------------------------------------------------
    Total computation time : 24.71 seconds(~ 0.01 hours)
    Writing informations into file pi.txt

    so meltdown makes next to no difference for this benchmark

    16.11 seconds

    i5 4690k 3.5ghz

    Pretty sure I have it overclocked, but Windows says it's at 3.5
