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.
In each of our tests we can clearly see how the better codec outperforms the lower models. In this case, the ASUS and ASRock have the edge over the others.
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.
As mentioned in the bulk of the review, the MSI Z77IA-E53 struggles with USB 2.0 speed. The XFast implementation by ASRock puts it on top, however without the XFast software the ASUS gets top honors.
Bars in orange indicate non-chipset USB 3.0 ports coming from controllers.
For USB 3.0, both ASUS and ASRock have utilites at their disposal to increase throughput. As mentioned in previous reviews, the ASRock implementation prioritises bulk transfers, whereas the ASUS implementation significantly boosts small file transfers. Without these features, the ASUS tops the copy chart, but only just.
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.
Our magical number for DPC Latency with modern technology is 200 microseconds, which every board manages to do except the EVGA (and the EVGA does not miss by much).

Thanks for the great comparison review!It looks like there is a little mistake in the spec list for the Asus board, which shows it having a mini-PCIe connector. I would love it if it did, but I didn't see it on the board and it isn't mentioned in other spec lists.
It is important to me because I would ideally need connection for both a graphics card and a sound card (which I believe I could do through a mini-PCIe to PCIe x1 adapter if needed). This makes the EVGA Stinger the choice for me here, though the Asus board is the one I would prefer to buy.
I am truthfully a little disappointed in the EVGA board, which seems all too common with EVGA products in general these days. Great support is still there, but I'd rather they build bleeding edge components and not have to find out whether or not their support is as good as people say it is. The Stinger is a good board to be sure, and the Intel LAN alone puts it in the category of "will buy" for me, but I was hoping it would be something that would match or beat the Asus P877-I, and it just doesn't.

When you take overclocking out of the equation, B75 has it all, for the price just a tiny bit north of the old H61 chipset. Support for IB features (1600Mhz DDR3, PCI-e 3.0), Native Sata III, USB 3.0.It wasn't intended for the DIY market but fits the bill perfectly in my opinion. Only the very very few who need to OC, +16Gb ram or multiple SSD's @ full 6 Gb/s need the Z77 chipset.
The only thing is, that us mere mortals can't predict is, if a much cheaper chipset is used, did the OEM also cheapskate on the critical parts to? I would love to see some in-depth component analysis which I see for example, when a PSU is taken apart.
Which components are used? how well is the soldering done, does it still work at a sauna lanparty, etc.
I might be alone in this, but I would find that much more valuable information than all the performance benchmarks together (race to the bottom, be dammed!).
Including the northbridge in the CPU made motherboard and CPU reviews so predictible (or borring).Since then, I'm only interested in stability, ease of installation (nicely covered) and practical use (fan controll, MEM compatibility ect).
<offtopic> Oh I loved the XP-m 2500+ siverpainting 2001 era where you actually could get a noticeable improvement of performance and not necessarily have to sacrifice stability or risk bankruptcy</offtopic>

i picked up an asus p8z77-i deluxe/wd before christmas and made a beast gaming computer out of it with an i5-3750k OCed to 4.5ghz and a gtx670 =]vanwazltoff - Tuesday, January 1, 2013 - link

Loved the POST screen measurements and the DPC latency testing. Something you dont see every day. Actually Ive never seen it, and yet I always wanted to know those.However I am not really interested in the Z77s, since they have a horrible layout for my needs. Only the Asus one comes close to what I need, but I just dont buy Asus anymore because of several very bas experiences.
So, I wish you would also test the B75 and H77s.

I love the features of this Asus mobo, but i want to use it in a really small form factor case like the Antec ISK 110 VESA Case.http://www.anandtech.com/show/6192/antec-isk-110-v...
I'm just worried that the height of the VRAM board would prevent it from using it with this case.

I still opted for the Gigabyte Z77N and love it...Sivar - Wednesday, January 2, 2013 - link
Does this refer to the ALC889 playing an audio file encoded at 192KHz?If so, does it really matter? Failing a test is never a good thing, but I know of no widely available 192KHz audio source, and such a source would have no benefit, nor would a 96KHz source.

I am a happy user of the AS Rock board in a silent HTPC. It works exceptionally well. However it is clear that some work still needs to be done on motherboard design.MSata on back is excellent - now can we have it as SATA 3 because the better MSata SSDs are all Sata 3.
Placement of Sata connectors is often awkward on these boards. On edge and at right angles please.
Similarly I would love it if someone either did the 24 pin ATX power connector at right angles or someone manufactured a right angled converter that did not require de soldering the motherboard connector. Cable management in Mini-OTX is very hard and that would really help.
Finally, careful choice of RAM can eliminate issues Ian had about the closeness of the CPU socket preventing the use of many after market coolers. I use the Samsung green low profie memory, which is so low that any after market cooler can be used (and runs at 1.35v, is an unbelievably good overclocker and reasonably priced!)

As has been mentioned previously, the H77 chipset is great for those who do not need overclocking. I've used the Intel DH77DF, and I heartily recommend it. Since the DH77DF has an eSATA port (not too common), I've even been able to keep an eSATA dock that I used before USB 3.0 was more readily available. If you install this board into a Fractal Design Node 304 case, you can use all of the SATA ports as well. I've used it with a Silverstone SG05 case, and the loudest part of my setup is the fan on the graphics card (Radeon 7850).One thing I've noticed, though, is the relatively low mic input from the front audio. Not sure if this is common to the Realtek ALC8xx chip series, but even after boosting the gain in Win7 to +30db, it still isn't quite as loud as an older AMD board I previously had (which didn't need a boost at all).
