3D Movement Algorithm Test
The algorithms in 3DPM employ both uniform random number generation or normal distribution random number generation, and vary in various amounts of trigonometric operations, conditional statements, generation and rejection, fused operations, etc. The benchmark runs through six algorithms for a specified number of particles and steps, and calculates the speed of each algorithm, then sums them all for a final score. This is an example of a real world situation that a computational scientist may find themselves in, rather than a pure synthetic benchmark. The benchmark is also parallel between particles simulated, and we test the single thread performance as well as the multi-threaded performance.
With our main comparison point being the dual module Trinity A10-5800K processor used in the F2A85-V Pro, we can safely say that single threaded performance on the Intel side is second to none – even when comparing a 3.3 GHz Intel part to a 4.2 GHz AMD part in a full FP workload.
When it comes to multithreading, due to the FP nature of the benchmark, the A10-5800K is essentially dual core due to its FP unit allocation. Thus comparing the i3-3225 with Hyperthreading to the A10-5800K gives a 50% bonus to the Intel processor.
WinRAR x64 3.93 - link
With 64-bit WinRAR, we compress the set of files used in the USB speed tests. WinRAR x64 3.93 attempts to use multithreading when possible, and provides as a good test for when a system has variable threaded load. If a system has multiple speeds to invoke at different loading, the switching between those speeds will determine how well the system will do.
It should be noted that WinRAR does like faster memory – thus the comparison points here show an A10-5800K @ DDR3-2400 10-12-12 against an i3-3225 @ DDR3-1600 9-9-9. Despite the Intel chip having a CPU and memory disadvantage, it still manages to perform our compression test 39 seconds quicker than the AMD chip.
FastStone Image Viewer 4.2 - link
FastStone Image Viewer is a free piece of software I have been using for quite a few years now. It allows quick viewing of flat images, as well as resizing, changing color depth, adding simple text or simple filters. It also has a bulk image conversion tool, which we use here. The software currently operates only in single-thread mode, which should change in later versions of the software. For this test, we convert a series of 170 files, of various resolutions, dimensions and types (of a total size of 163MB), all to the .gif format of 640x480 dimensions.
Xilisoft Video Converter
With XVC, users can convert any type of normal video to any compatible format for smartphones, tablets and other devices. By default, it uses all available threads on the system, and in the presence of appropriate graphics cards, can use CUDA for NVIDIA GPUs as well as AMD APP for AMD GPUs. For this test, we use a set of 32 HD videos, each lasting 30 seconds, and convert them from 1080p to an iPod H.264 video format using just the CPU. The time taken to convert these videos gives us our result.
x264 HD Benchmark
The x264 HD Benchmark uses a common HD encoding tool to process an HD MPEG2 source at 1280x720 at 3963 Kbps. This test represents a standardized result which can be compared across other reviews, and is dependant on both CPU power and memory speed. The benchmark performs a 2-pass encode, and the results shown are the average of each pass performed four times.

I like the placement of the 24 pin power header. My E350 case has the external power button right where it interferes with the power header toward inside of front panel. Also I like testing with i3. I go for lowest power consumption. I use a picoPSU and would like to see these tested with that psu. For me it is a USB world. all I care about is HDTV, low power and USB3. If you want to overclock perhaps you should go with a bigger board.Pcosx - Wednesday, November 7, 2012 - link
Why don't anybody makes a z77/h77 board with dual link dvi output? Is it so much more to make one?Dug - Friday, November 9, 2012 - link
Good question, and it would be nice to know the limitations of video output on these motherboards with different connections.Znarkus - Thursday, November 8, 2012 - link
Why present POST time with two decimal points, if there is a 1 second error margin?IanCutress - Friday, December 7, 2012 - link
Results from my stop watch. Error margin is a large overestimate of what it might be from human error, not hardware error. For each reading I take 3 measurements, and more often than not I get all three in the same 0.10 seconds.Ian

I would love to know how well this is supported under Linux? No real need for Benchmarks just put Ubuntu, Mint, or Fedora on it and see if the Network, WiFi, Video, Sata, and USB all work.Also Hackintosh compatibility would be nice but maybe too out their to be worth your time but would be very cool.

The spec table shows z77 chipset, should be h77?dingetje - Wednesday, November 21, 2012 - link
please include the EVGA Z77 Stinger Mini-ITX Motherboard in the upcoming article.thanks

Thanks for the detailed review. Could you give an idea of what the audio benchmark actually means? Do those results indicate that the audio quality is good or bad?A review of the Gigabyte B75 ITX board shows that the audio quality is poor, and the Gigabyte Z77 board not much better. They also use Rightmark Audio Analyser, but represent the results differently so there is no way to compare. Please can you give your audio test results in dB(A) so we can compare?

It would also be good to have a wider comparison of the power draw, say with the Z77 ITX boards you reviewed.

have problems with the graphics card!! Works fine with the graphics BIOS settings at auto but does not work with BIOS settings with graphics set to PEG and changed the miscellaneous settings from Auto to Gen1,Gen3 but still didnt work. Tested it on different systems and it seems to work fine but does not work only on this mobo, the mobo itself is fine again. The graphics card is a HD6670 1GB DDR5.
