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.
It 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.
Not much to say here; the numbers are very close indeed. We have a separation of only 4 seconds at stock speeds and one of 15 when overclocked (due to the HDD slowdowns). Still, it is pretty impressive to see the 770 perform so close to the 890FX.
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.
The 870A Fuzion is a little slower than the M4A89TD, again probably due to a combination of memory and HDD performance on the 770 chipset. It does manage to perform quite well when we kick the CPU up to 3.9GHz, though.
