Rightmark Audio Analyzer 6.2.5

In part due to reader requests, we are pleased to include Rightmark Audio Analyzer results in our benchmark suite.  The premise behind Rightmark:AA is to test the input and output of the audio system to determine noise levels, range, harmonic distortion, stereo crosstalk and so forth.  Rightmark:AA should indicate how well the sound system is built and isolated from electrical interference (either internally or externally).  For this test we connect the Line Out to the Line In using a short six inch 3.5mm to 3.5mm high-quality jack, turn the OS volume to 100%, and run the Rightmark default test suite at 48 kHz, 96 kHz and 192 kHz.  We look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.

RightMark Audio Analyzer: Dynamic Range (16-bit)

RightMark Audio Analyzer: THD + Noise (16-bit)

In our limited audio test, the G1.Sniper M3 does come out better off than the SupremeFX III, but in order to get there we had to disable the majority of the add-in software that comes with the Gigabyte in order to get the test to even run at anything more than 48 kHz.

USB 3.0 Backup

For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 240 GB OCZ Vertex3 SSD with a SATA 6 Gbps to USB 3.0 converter.  Then we transfer a set size of files from the SSD to the USB drive using DiskBench, which monitors the time taken to transfer.  The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the WinRAR test. 

The Maximus V Gene is ahead in terms of USB 2.0 speeds and efficiency.

Similarly in USB 3.0, the ASUS takes the lead.  As the ASUS has USB 3.0 Boost and an ASMedia controller for extra USB 3.0 ports, we can see that any setting hits the high echelons of our USB 3.0 test.  It is worth noting that ASUS have the top eight spots in our most recent USB 3.0 data.

DPC Latency

Deferred Procedure Call latency is a way in which Windows handles interrupt servicing.  In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority.  Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line.  So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled.  If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks.  Having a bigger buffer and correctly implemented system drivers obviously helps in this regard.  The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes.  Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - under 500 microseconds usually gets the green light, but the lower the better.

DPC Latency Maximum

ASUS typically do very well in DPC Latency, and the Gene is no exception – 81 microseconds was actually a tall peak compared to a baseline around 35-40.  Gigabyte’s result required EasyTune6 to be turned off, otherwise the peak was nearer 500 microseconds.

    as an owner of the g1 sniper m3 I have to say some of your comments are valid -should have more sata ports very annoying , pciex 8x x8 layout is brilliant no card overheating running 2 evga 680 classifieds -but the sound for gaming is underestimated it is fantastic and gives you positional awareness of your enemy better than the Asus I have the maximus 1V genieZ and Maximus 1V extreme Z in other systems -love the extra features -but still anyone looking the sniper is great for gaming -posters a waste of time
