Real-world testing allows us to see how well a product will perform when used in the same manner as it would be in your house or office. It is an important side to performance testing as it can uncover hidden glitches in the way a product performs.
This is especially true when testing a mainboard; there are so many components of a board that have to interact that any problems between parts can cause a failure of the whole.
For real-world testing we use some common applications and functions. We test with LightWave 3D for rendering performance, AutoGK for transcoding from DVD to AVI, and two games for gaming testing.
Rendering of 3D Animation is a system intensive endeavor. You need a good CPU, memory, and HDD speed to get good rendering times. For our testing we use LightWave 3D. This software from Newtek is an industry standard and has several pre-loaded scenes for us to use.
Lightwave 3D seems to back up the supposition that the H55N-USB3 is not able to deal with the 875K properly. This could also be the reason for all of the overclocking failure warnings we saw before we updated to the F4 BIOS. It seems like there is more work to do.
AutoGK stands for Auto Gordian Knot; it is a suite of transcoding tools that are compiled into an easy to install and use utility. It allows you to transcode non-protected DVDs and other media to Xvid or Divx format. For our testing purposes we use a non-DRM restricted movie that is roughly 2 hours in length. This is transcoded to a single Xvid AVI at 100% quality.
Not too bad of a showing here for the little H55N-USB3. We are still guessing that it is not quite built for the 875K as the performance is not exactly where it should have been with the HDD performance we saw.
