Although the Intel Z77 Express chipset has been available for a while now we chose to wait until the official launch of Ivy Bridge to begin our reviews. After all the Z77 with Panther Point was designed to get the best performance when tied with Ivy Bridge so why not show that off first. To kick off our coverage of the Z77 we deiced to try out Intel’s reference design in the DZ77GA-70K. This performance desktop board from Intel is a great starting point and will give us the feel of how Intel meant things to work. So let’s get to it shall we?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.
Again we see the improvements of the CPU more than the actual motherboard, but we can also see some of that her as well. The Intel DZ77GA-70K manages to stake out a spot at the top of the list for stock performance, this time we do not see the same scaling issues we saw under Cinebench which is a good thing.
CyberLink Media Espresso 6.5 -
After having various issues with AutoGK and Intel CPUs with more than four cores we have changed our Media Encoding test to use Media Espresso from CyberLink. Although this new utility does not have the same ability to transfer directly from DVD it is still a good test to transfer different media types into a usable format for your iPad, iPod, or other media player. Our test involves using multiple (Six) 20 minute media files and transcoding them for an iPad. This gives us a very good indication of how well a motherboard can handle this type of work load.
No surprises here as we see the AVX sporting Ivy Bridge run away with the show. It also does not hurt that the GPU is coming into play to help speed things along
