    Benchmarks - Synthetic

    SiSoft Sandra
    Sandra is a software collection of synthetic benchmarks that will give us a basic idea as to what a system is capable of. It should be noted that SiSoft numbers change depending on what version you have installed; these were recorded using Sandra Professional Version 17.25.2011.1
    One of the most difficult things about doing reviews is finding some kind of common ground to establish a benchmark on so that when we say something is good our readers know it is based on something they can try themselves.  In the cause of audio reproduction there are too many factors to consider such as hearing quality, sound equipment (speakers) and room dimensions so we are turning to the RightMark Audio Analyzer to give us a set of audio specs.  We will then use those numbers to determine what kind of audio quality you can expect.

    This test was performed using a loopback cable which is basically a jack that connects the analog line-out plug back into the analog line-in.  That way we can remove almost all of the variables and concentrate on what is actually being reproduced and recorded.

    Frequency response (from 40 Hz to 15 kHz), dB:  +0.06, -0.17
    Noise level, dB (A):  -89.6
    Dynamic range, dB (A): 89.4
    THD, %:  0.130
    THD + Noise, dB (A):  -52.8
    IMD + Noise, %:  0.255
    Stereo crosstalk, dB: -89.4
    IMD at 10 kHz, %: 0.322
    General performance Good

    Color coding indicates good to bad, Bright green = Excellent - Bright Red = Poor - Black = Good
    Synthetic Conclusion
    Synthetic performance never really tells the entire story, but is a good indication of what the system would probably be capable of doing under the right conditions.   The Core i7 980X is still a very powerful processor with a slow memory controller.

    The new Rightmark audio benchmark is a great tool for exposing audio specs for the various chips and software used and read much like if you were buying an amplifier or sound system for your house.  What you can take away from this is that the sound quality is "good" for an onboard audio solution despite the rather poor performance in THD Noise.  Looking back on some of our past motherboard reviews we can say that the X58A-OC does have some extremely good sound specs despite the limited analog connection. 

    We did color code some of the other numbers to give you an indication as to what each of the numbers mean.
