Normally when a new chipset hits the market we like to try and get a motherboard from one of the major companies for use in our reviews and initial testing. This goes for any new CPU regardless of if it is AMD or Intel. The reasons are pretty simple; the first is that realistically not that many people but Intel reference products. You get some that will, but the majority are going to buy from Asus, Gigabyte, MSI or one of the other players. This is not saying that Intel boards are not good products; it is just that most consumers have their favorite brands. However we wanted to try things a little differently with the launch of the X79 chipset. We have decided to take a first look at Intel’s reference motherboard and see how well it performs. As with everything we do there are multiple reasons for this. One is we want to see how Intel’s implementation of three-way SLI using the CPU for all PCIe lanes works and we also wanted to see what the overclocking envelope turns out to be. This will give us a great baseline for the reviews of other X79 motherboards in the weeks ahead. So with all that out of the way lets dive into Intel’s X79SI Siler (insert Heroes Reference here).
Section II - Performance Tests, Synthetic -In this section of testing we cover the synthetics. These are tests that run a scripted sequence of internal APIs or that use another installed application to perform a series of scripted events. They are great in that they can provide reproducible results across various platforms. On the down side, synthetic tests can be fooled with driver tweaks and optimizations. In some cases it is necessary to rename the .exe file to something generic to discover if this is the case. In any event when this is needed (when a test shows a drastic difference in performance over the renamed exe) we will note this and show both results for comparison. PCMark7 -PCMark7 is the latest general performance test from FutureMark. As each generation of this benchmark has evolved and developed we have watched them add more and more realistic tests to this suite. With this generation we find more media tests, (audio and video transcoding) moving of large files, multiple web page rendering, and much more (the even added DX10 gaming). We use the Overall Performance and Common Usage suites in our testing.For PCMark7 we found that there was one other board that was able to out-perform the X79SI even with its quad channel memory and the much more powerful CPU. This could be an issue with the test itself though and not anything to do with the board. We will be keeping an eye on this to see if anything develops from it.3DMark 11 -3DMark 11 is the other Futuremark test that we run on our motherboards. This test simulates the typical tasks that a GPU (and system) would have to perform to provide you with a good gaming experience. It is based on the DX9, DX10 and DX11 engines but can only be installed on Windows Vista or later. The suite of tests covers DX9, DX10, and of course DX11 rendering; it also covers AI computations and physics. That’s right I said Physics the latest version of 3DMark uses a Havok physics engine. This removes the advantage that nVidia had with 3DMark Vantage. In 3DMark 11 we are beginning to see the potential of the new combination of the X79 chipset/Motherboard and the 3960X CPU. Here we find that the CPU based Physics scores are simply off the charts. HyperPi 0.99b -HyperPi is a front end application that allows you to easily run multiple instances of the SuperPi application. SuperPi, for those that are not familiar with it, is an application that measures the time it takes to calculate the number Pi out to as many as 32 million places. This calculation is then checked and run multiple times (up to 24 for a 32M run). This test stresses the CPU, Memory and HDD as data is handed off between the three. If there is a weak link, HyperPi will show it. For our testing we run the 32M test on as many cores (and threads) as the CPU has available. The slowest CPU time is then recorded. If you were not convinced with the memory performance tests from SANDRA and Everest then here is further proof that the new Quad Channel memory support on the X79SI is something impressive. Normally with a 6 Core CPU and Hyper Threading we do not expect very quick HyperPi times. The amount of data that has to travel back and forth is simply too much. However with the extra room available in the memory bus our HyperPi times are excellent. Only the non-hyper threaded CPUs from Intel are able to do better.Cinebench R11.5 -Cinebench R11.5 is the 11th release of Maxon’s rendering test. This test is based off of the Cinema 4D engine, which is one of the industry standard tools for digital animation. It is a powerful product with many different modules that can be “plugged” into it to increase its effectiveness. With Cinebench you get to see how your computer would do using this application. There are two tests; one tests the CPU’s ability to render an image across multiple cores or threads. The other tests your systems ability to handle OpenGL based rendering. In Cinebench R11.5 we see the raw power of the CPU and the new quad channel memory. We were able to get stock scores that were faster than many of the overclocked scores. That is something pretty impressive.
