After a look into the design and features of the Gigabyte Z68X-UD3H we are now diving into how well it performs. Unlike the MSI Z68A-GD80 we do not have any indications that we will run out of PCIe lanes, however we are still a little concerned about how well the Z68X will perform when we drop in the HD5870. We are also more than a little curious to see how the touchBIOS will work on the real world. So, let’s dive in and get to testing the Gigabyte Z68X-UD3H.
Section III - Performance Tests, Real-World -Here we have two tests that are designed to put the performance of the motherboard and its subsystems to the test. Both require good CPU, Memory, HDD and even to a lesser extent audio and network performance. The two tests we chose were Lightwave 3D 9.6 and AutoGK 2.55. We will be adding at least one more real-world test to this battery in the near future, but for now these two cover quite a bit.Lightwave 3D 9.6 x64 -Lightwave is another industry standard application for 3D animation and rendering. It has a large tool base and the rendering engine is highly threaded (when using the right render model). This application is also capable of expanding to 4k resolutions as well as ray tracing for rending the light sources. For our testing we use frame 470 of the Pinball scene found in the LW 9 Content folder. This uses the newer perspective camera that is better suited to a multi-CPU/Core environment. This camera style also uses ray tracing and a much improved anti-aliasing method. Settings are shown below in the attached screen shot. Of course these are single frame renders and they are not a complete picture; for that you have to take into account the number of frames an average project would have. In a typical 30 second commercial you will have around 840 to 960 frames (at 28 – 32 FPS) this means that you have to multiply the time of a single frame by that number just to get a vague idea of how long that 30 seconds would take. This is because each frame will have a different render time based on complexity.Well, looks like the performance discrepancies we saw with Cinebench affect our other rendering test Lightwave 3D. This is actually a little odd considering the level of memory and HDD performance we saw. We will have to dig a little deeper to find out the root causes for this, although it could all boil down to a flaky tuning in the BIOS or a flaky driver. We have a feeling it is the former and not the later.AutoGK 2.55 Transcoding -AutoGK is a transcoding software that is really multiple parts combined to make an easy to use whole. It combines, items like FDD Show, Xvid encoder, Virtual Dub and others for use in converting one media format to another (usually Xvid AVI). It will not transcode copy protected DVDs or Bluray discs yet (you still need a decrypter for that). But it does an excellent job on everything else. For our testing we use a 2 hour movie that has been placed onto a standard definition DVD for playback; we then transcode this DVD to a 100% quality AVI with the original audio intact. This puts a strain on the CPU, Memory, HDD and the attached DVD ROM drive.We know that Intel is moving towards a much more multi-media oriented experience. Our AutoGK times represent this very well. The times are even better when we just run the Core i7 all by itself. This is due to some of the optimizations Intel has put into the CPU. This is something we are going to be taking a closer look at in the near future.
