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).

Thank you so much for this Z77 roundup as I'm currently shopping for a new mobo and have been piecing together reviews from various sites. But as usual I always check here first, then Tom's, then Hardocp (in that order). Keep up the great work in 2013!Aikouka - Monday, December 31, 2012 - link
Ah, if only I held off on building my silent HTPC for a little bit longer. The hardest part about working with a Streacom case (other than building it) is finding a good motherboard that doesn't put too much in the way of the heat pipes. That's one reason why I was considering going with a board with mSATA, and I'm pretty certain that I stumbled across that ASRock board. Unfortunately, I looked at the photos, and didn't see a mSATA port, so I passed on it. Who would have thought to look at the back? Boy, do I feel like a bit of a dummy now! =$Although, speaking of the back mSATA connector, I recall seeing you touch on it on the recommendation page, but do you think it would work well on most cases? If I remember correctly, mSATA drives are fairly thin, so it might be fine. Going back to the Streacom, it does look like the ASRock offering would work well in regard to clearance even disregarding the mSATA port as the light gray SATA ports should clear the heat pipes. The USB3 port won't though.

I built 2 asrock builds with the msata as the only drive. btw this z77 review with no regard to oc is pretty weird.I have a 3770k with a hd7970 gpu and an msata in a small case the cooler master elite it is a very fast powerful machine. I use the asrock and love it. it does have a flaw the msata slot is sata II

I have i3-3225 (the same as in the article). In my opinion, for the money, the best is ASUS P8H77-I.It does have 6 SATA ports - a must for a file server. So, basically install Windows 8 on a SSD, add HDDs and create Storage Space - 5 SATA will allow you to create software RAID 5, without the need of SATA extension controller. BIOS is nice and stable. The board is $100 on Newegg.
The ASUS Z77 Deluxe is nice, if anybody needs all the additional functionality in a small form factor. However, only 4 SATA - means no good for video, file, backup server. You get the "overclocking" ability though. I doubt how practical is overclocking into so small space, probably to a handful of people. Teh board costs $185.
So, I would say $100 is better than $185, plus you get all the 6 SATA ports - priceless.

Not everyone who games wants to have a huge tower. I've built more then one system based around the silverstone FT03-mini that runs a 3750k / Z77 deluxe-i and a GTX 670.I bring mine to lan parties and people are amazed at the power in such a small box, and it's just as fast as any desktop single GPU alternative.

ASUS P8H77-I is a mini ITX board - the cheaper variant of the reviewed deluxe board. It costs $100.ggathagan - Wednesday, January 2, 2013 - link
I agree; the H77 makes much more sense for most ITX builds.I built a system with the P8H77-I, a GTX670 and the FT03-MINI.
I don't think the daughter card of the Z77 Deluxe would have fit in the case.

I registered here because the reviewer is lamenting that some boards use the ALC889 instead of the ALC892 codecs.The 889 like the 882 before it and the 898 after it is a much better codec than the 892.
The 883,888,892 codecs are the cheaper low performance DAC/ADC chips.
I would buy a board with the ALC889 or preferably the ALC898,but not with the ALC892.
all the best in 2013

too bad I already ordered mine last week ... MSI Z77IAto tell the truth, i don't really mind [ at 136€ its a bit pricier than asrock with my supplier]
the conclusion for this board seems a bit biased to me
but hey, if you're not looking for a tiny powerhouse, you don't need z77
- in SUGO 05(and most small cases), MB is horizontally and PSU is above it, so cables and airflow will always be nasty
- using a discrete GPU, you don't care about not having DVI or DP
- no additional controller (USB/SATA) -> I don't plan on using more than 2(won't fit into case), so why bother?
//btw is the SATA 6/3/m correct 2+2? shouldn't be also 2+2+1?
- and if I'm to take the "military grade" stuff at least half seriously, ...

Do the post times include those pesky AHCI driver loading screen? I hate that it adds so much more to the boot process.
