System Benchmarks

Rightmark Audio Analyzer 6.2.5

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 speaker volume to 100%, and run the Rightmark default test suite at 192 kHz, 24-bit. The OS is tuned to 192 kHz/24-bit input and output, and the Line-In volume is adjusted until we have the best RMAA value in the mini-pretest. We look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.

Dynamic Range for the Z97 Extreme6

Rightmark: AA, Dynamic Range, 24-bit / 192 kHz

Rightmark: AA, THD+N, 24-bit / 192 kHz

While the Dynamic Range measurement is on par with the other ALC1150 motherboards we have tested, the THD+N is low, coming in above -80 dBA. In the graph above we can see harmonics over the 1 KHz pulse which may be a contributing factor.

USB 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. In an update to pre-Z87 testing, we also run MaxCPU to load up one of the threads during the test which improves general performance up to 15% by causing all the internal pathways to run at full speed.

USB 3.0 Copy Times

ASRock no longer package its motherboards with XFast USB, and it would seem that the lack of a Turbo mode pushes the USB 3.0 performance in the wrong direction.

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 - less than 500 microseconds usually gets the green light, but the lower the better.

DPC Latency Maximum

Our previous review, the Z97 MPower Max AC had struck a new record for DPC Latency however the ASRock Z97 Extreme6 takes the crown with a very impressive 39 microseconds. This pretty much confirms that there was an issue with Z87 which has been fixed with Z97, although perhaps at the expense of POST time.

    The Gen2 M.2 x4 PCIe looks very impressive. Its too bad that Asrock did not include this in their mITX offering. Reply

    Regarding the Dolphin benchmark- you wrote:
    "Results are given in minutes, where the Wii itself scores 17.53; meaning that anything above this is faster than an actual Wii for processing Wii code, albeit emulated."

    This should read "... meaning that anything below this is faster than..." - right?

    Bad choice of words - anything 'above on the graph' would be faster based on the orientation of results. I've updated it to remove the ambiguity. Thanks for pointing it out :)

    The overarching conclusion from this review - Intel needs to put far more PCIe 3..0 lanes on their CPUs and chipsets if we want motherboards where connectors don't play musical chairs with each other for bandwidth. Also, Samsung needs to make the XP941 a retail product right now! Reply

    I think the reasoning behind an either/or situation with M.2/SATAe is sound - the consumer most likely will not require 2 high end SSDs, and will go with one that is either M.2 or SATAe, the rest can be served via normal SATA ports.

    Also I think SATAe, while a great idea, will lose out to the convenience and capability of M.2; SATAe would have been great 2 years ago but now M.2 is here it is absolutely perfect for an OS drive, cutting down on not just size but cabling.

    Agreed about SATAe, especially since (a) SSDs don't really need that much circuit board area and (b) A RAID array of two SATA SSDs offers at least as much theoretical bandwidth as a SATAe while taking up the same amount of ports on your board. Reply

    Exactly my thought. So why have SATAe???? Its great that it uses PCI but it doesn't really offer anything that we couldn't already do.

    As you've said, "A RAID array of two SATA SSDs offers at least as much theoretical bandwidth as a SATAe while taking up the same amount of ports on your board".

    There seems to be a lot of stupid decisions being made regarding ports. DDR4 is another example of a useless upgrade.

    "A RAID array of two SATA SSDs offers at least as much theoretical bandwidth" But your are losing random performance when going RAID and increase the chance of a disk failure. Why would you even compare them? Reply

    Ian,

    Can you explain to me why no mainboard manufacturer is using 4 lanes from the chipsets PCIe 2.0? I mean that would be enough for the Samsung SSD and still has room left. I mean what do I gain from all those SATA and USB ports? Who is actually using all of them?

    Right now I have to choose between either a slow M.2 slot because they only allocate 2 lanes or I can go with ASRock which feels like overkill and takes away CPU PCIe lanes.
