Foxconn P67A-S Motherboard Review

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 thing 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 wlll 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.

Specs
Frequency response (from 40 Hz to 15 kHz), dB:  +0.09, -0.13
Noise level, dB (A):  -87.4
Dynamic range, dB (A): 87.2
THD, %:  0.131
THD + Noise, dB (A):  -52.8
IMD + Noise, %:  0.255
Stereo crosstalk, dB: -84.6
IMD at 10 kHz, %: 0.305
General performance Good

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.   Our little Sandy Bridge chip is really showing a massive improvement over the previous generation, in fact in most cases its beating our Core i7 920 (with turbo disabled)

The new Rightmark audio benchmark is a work in progress, seems the full chart is a little difficult to understand.  What you can take away from this is that the sound quality is "good" for an onboard audio option.
