Gigabyte G1-Killer Sniper 2 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 17.77.2011.10

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.

Specs
Frequency response (from 40 Hz to 15 kHz), dB:  +0.10, -0.22
Noise level, dB (A): -91.4
Dynamic range, dB (A): 91.3
THD, %:  0.082
THD + Noise, dB (A):  -56.8
IMD + Noise, %:  0.171
Stereo crosstalk, dB: -90.8
IMD at 10 kHz, %: 0.351
General performance Good

Color coding indicates good to bad, Bright green = Excellent - Bright Red = Poor - Black = 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.   The Core i7 2600K is a very powerful processor despite only having a dual channel 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.  Those of you who are skeptical of onboard audio solutions will be surprised to know that the Creative APU used on the G1-Killer has the best specs of the boards we have tested even though the end result is still "good".  We did color code some of the other numbers to give you an indication as to what each of the numbers mean.

We need to mention that during our testing we originally had the default effects enabled which totally destroyed the audio summary knocking the overall scores down to "Average".  We suspect this has to do with the software algorithms that are used to simulate surround sound over 2 speakers since crosstalk and noise levels were extremely poor.  Once these features were disabled the testable sound quality went back up to the levels you see above.
