Testing & Methodology

We’ve expanded our testing suite considerably since the X79 chipset release, and will continue to use the same methods for most of the motherboards and CPU’s we test. In the interests of thoroughness and accurate results, we run each test at least three times, and some tests more than that. We average the total of all the tests from each benchmark then report the average here.

The OS we use is Windows 7 Pro 64bit with all patches and updates applied. We also use the latest drivers available for the motherboard and any devices attached to the computer. We do not disable background tasks or tweak the OS or system in any way. We turn off drive indexing and daily defragging. We also turn off Prefetch and Superfetch. This is not an attempt to produce bigger benchmark numbers. Drive indexing and defragging can interfere with testing and produce confusing numbers. If a test were to be run while a drive was being indexed or defragged, and then the same test was later run when these processes were off, the two results would be contradictory and erroneous. As we cannot control when defragging and indexing occur precisely enough to guarantee that they won’t interfere with testing, we opt to disable the features entirely.

Prefetch tries to predict what users will load the next time they boot the machine by caching the relevant files and storing them for later use. We want to learn how the program runs without any of the files being cached, and we disable it so that each test run we do not have to clear pre-fetch to get accurate numbers. Lastly we disable Superfetch. Superfetch loads often-used programs into the memory. It is one of the reasons that Windows occupies so much memory. Vista fills the memory in an attempt to predict what users will load. Having one test run with files cached, and another test run with the files un-cached would result in inaccurate numbers. Again, since we can’t control its timings so precisely, it we turn it off. Because these four features can potentially interfere with benchmarking, and and are out of our control, we disable them. We do not disable anything else.

One thing to note is that we are revamping our testing method in order to better represent motherboard performance and offering to you guys the consumer. Also we want to make it an easier read for you without miles of endless charts. Please feel free to provide feedback on what you think as many benchmarks will be shuffled or removed completely.

Test Rig

Test Suite

We will use the following applications to test the performance of the Z87 Chipset (Motherboard, Processor).

PCmark 7

First up is PCMark and to my surprise this boards efficiency is actually very good, it knocked out some of the highest numbers I have seen to date for the overall PCMark score.

3DMark 11

Here you can see that the Gigabyte board pulls no punches in the graphics performance area as it pulls very nice numbers and when considering the price this is looking more and more like a hell of a deal for those looking for a awesome 1-2 card board.

SuperPi

This tests single threaded performance and clock efficiency by processing digits of the number pi. Going from the previous gen Z77 to Z87 yields a nice efficiency jump clock for clock, but we still feel this could be a premature result. The result with the OC Board is rightfully improved as the efficiency shows with some better performance numbers than even the top performing Gigabyte boards we had tested already.

Wprime

WPrime is similar to Superpi, but is multi core aware and you can set the core count. We used 8 threads to take advantage of the 4770K’s HyperThreading ability. Here you can see that the efficiency in multi core processing improves as you can see a pretty nice gain going from Z77 to Z87, and even more so when overclocked. We are quite excited to see what this platform can do as we get our hands on more boards to test real world performance.

On the Gigabyte Z87X-OC pulls some very good numbers and almost bests the Intel platform when overclocked which honestly is quite the feat being as the full line of boards we have tested so far have not beaten it yet.

Cinebench R11.5

X264HD

Transcoding has become more popular now and the latest Sandy Bridge processor added support for AVX instruction for faster video transcoding. With that you can see that going from Ivy Bridge to Haswell can net you some very good gains, especially a 2FPS gain on 2 Pass. This tells us that overall optimizations to the new platform are present and working very well. This is shown to an even greater extent on the OC board as the efficiency pushes an even stronger result both stock and overclocked.

Truecrypt 7.1

TrueCrypt is a real world application that gives a good indication of the true performance of our latest processor. Here the new Core i7 4770K puts some definite room between itself and the outgoing 3770K with over a 22% performance increase, which means in the same time you can get a lot more work done. The OC Board once again shows strong but well there’s only so much you can do on a test lke this so the improvements are small but they still show what the board is capable of on things beyond just benchmarks.

Unigine Heaven 2.5

Unigine Heaven is a benchmark program based on Unigine Corp’s latest engine, Unigine. The engine features DirectX 11, Hardware tessellation, DirectCompute, and Shader Model 5.0. All of these new technologies combined with the ability to run each card through the same exact test means this benchmark should be in our arsenal for a long time.

Unigine Heaven on a discrete GTX 680 gains about a single FPS, probably just due to the expanded performance with the overclock. For the most part, however, recent platforms are so efficient that there simply is no bottleneck for current gen card models.

Metro 2033

Metro 2033 shows drops slightly in comparison to the Intel when overclocked but the gaming performance appears slightly better when comparing stock to stock speeds. This could partially be due to the higher memory bandwidth numbers the Intel board was showing as it gives a bigger pipeline to work with.

Batman Arkham City

Discrete GPU results for the Gigabyte board are very good showing increases quite good over the reference Intel board and even more when overclocked which speaks well to the Gigabyte teams performance optimizations.

Sniper Elite V2

While Sniper Elite V2 shows very high max FPS on the Intel board when overclocked, but in reality that does nothing if its not consistent and with the OC board we once again see similar to the other Gigabyte boards we tested where maximum FPS did not spike as high but the average was higher which tells me taht the platform stays at a higher FPS more consistently compared to the peakiness or even possible jittering you might see from the Intel board.
