System Benchmarks
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 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.
Using the ALC892 for the Gryphon seems the right choice of codec, however it is limiting in terms of SNR compared to the ALC898 and above models.
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 Turbo boost provides an ample improvement in peak read speeds, although this does not translate in to much gain in the copy test.
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.
Once again the Z87 platform gives another 150+ result, showing that there is something fundamental with it causing a higher peak DPC than older Intel platforms.

I was kind of hoping for an analysis of exactly how TUF motherboards differ from the rest. Technical details, specific component lists with a look at their manufacturer specifications, you know -- hardcore Anandtech stuff.Yes, it has a longer warranty, but is that because the "TUF" voltage regulators are rated for higher temperature environments (and similar), or is it more a marketing gimmick?

Exactly! I actually strongly considered this board on my last build for a CAD workstation... Reliability and stability were primary factors. In the end, their marketing actually turned me off. The marketing seems to be more about appealing to G.I. Joe / Call of Duty fans with the over-the-top website, colors, and military lingo. I just wanted a "professional" geared board. I get the impression it might be a good board for less than ideal environmental conditions, still no idea if the board really would be any better in a typical office environment.HandsomeChow - Wednesday, February 12, 2014 - link
If you really want to see what components they are, just remove the top heatsink on the MOSFETS and there should be a product number on the Caps and the Mosfets and you can search them up along with the Inductors.jtd871 - Monday, February 3, 2014 - link
Bingo. Does the "armor" actually do anything worthwhile? Or is that just an expensive gimmick? I noticed also that the IO plate seems to have an open vent in it. => I think I see a potential path for dust entry into the armor! And how do you get enough cooling air to the heatsinks around the CPU if they're covered by the armor?! Downdraft cooler?khanov - Monday, February 3, 2014 - link
It's a great addition for people who frequently shoot at their pc's with bb guns. Also for those that open the side of the case and throw hard objects at the motherboard.Iketh - Saturday, February 8, 2014 - link

In terms of Heat dissipation, the aim from Asus is to keep external heat sources from conducting to the motherboard. Hence the Armour being made out of plastic. But the internal components on the motherboard also admit some heat so it is a double edged sword. The Armour is more of a Dust protector/Moisture shield. And yes there are potential airflow gaps that will allow dust to enter but it is much less dust compared to a motherboard without the Armourkyuu - Monday, February 3, 2014 - link
Have to agree with this. We need more info on what exactly the differences are between this and a "run-of-the-mill" Z87 board. Did they use different components (higher quality capacitors, voltage regulators, etc.)? Did they undergo more validation? Does the armor kit do anything worthwhile, and does it hamper cooling in any way?FractinJex - Monday, February 3, 2014 - link
Here....I have used several for work related builds and one for myself they are awesome!TUF Black Metallic capacitors, chokes, and MOSFETs are screened by seven rigorous military-grade tests to ensure superior lifespan even under the most demanding conditions.
The components used are of about server grade quality in other words its a bit better than a standard board/mid range board 100-250$ range...most boards these days are built to last but most do not come with 5 year warranty either...and someone whos been in the industry most boards are built to last just that so go more some go less etc...
Currently atm this and the genie are the best matx boards available to date.

"TUF Black Metallic capacitors, chokes, and MOSFETs are screened by seven rigorous military-grade tests to ensure superior lifespan even under the most demanding conditions." marketing speak much?
