    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
    RightMark Audio Analyzer
    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, -0.13
    Noise level, dB (A):  -92.3
    Dynamic range, dB (A): 92.4
    THD, %:  0.130
    THD + Noise, dB (A):  -52.8
    IMD + Noise, %:  0.256
    Stereo crosstalk, dB: -91.8
    IMD at 10 kHz, %: 0.322
    General performance Good

    Color coding indicates good to bad, Bright green = Excellent - Bright Red = Poor - Black = Good/Average
    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.   If you have been following the news of Ivy Bridge you will already know that the out of box performance is almost identical to a Sandy Bridge at the same speed.  Despite this the Core i7 3770K is still a very powerful processor and is currently highly regarded in the overclocking world for its ability to scale under LN2.
