We have taken our walk around of the Gigabyte 990FXA-UD5 and found we like the design and many of the features packed into the system. In the second half of our test we will be diving into what you can get out of it when you put in under the stress of rendering, gaming and general purpose computing. We do have concerns with this new product as it has really been built with a newer CPU in mind (one that is not ready as of this writing). Still one of the things that AMD has always worked on is backwards compatibility. With that in mind we are breaking out our Phenom II 1100T and getting ready for some testing.
Section II - Performance Tests, Synthetics -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.Unfortunately the 990FXA-UD5 with our 1100T did not do well with the tests in the PCMark7 suite. We were hoping for more, but it did not transpire. We would lay even money on the IMC inside the 1100T as the culprit here. 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. For 3DMark11 the 990FXA-UD5 does well in terms of overall system score, but when it comes to the CPU bsed Physics score it struggles to get through the test, again we would have to say that this is a memory issue rather than a raw power problem.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. Again we find another benchmark that shows slightly slower performance than the last generation. It is disappointing, but we do feel that some of this will change when we see Bulldozer hit, but we also feel that this can be corrected with some more tuning of the BIOS.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. Ok, now this is a little more like it. Here in the multi-threaded rendering test from Maxon we finally see the 990FXA-UD5 pull ahead of the other AMD boards. This means that there certainly is hope for the 990FX chipset. Again, our guess is that once we see Bulldozer hit the streets we will see some of the performance potential of the 990FXA show up.
