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.
Again we see the two new Phenom X4 CPUs drop back in the standings. The 975 BE is still faster than a Core i5 750, but that does not take Sandy Bridge into account yet either.
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 transcoding scores we find with the two new Phenoms are not impressive. Again this is mostly due to the slower memory performance that they have in comparison to the competition. If AMD can correct this issue we can see them discovering a serious performance gain.

This is a new test to TweakTown for CPUs, but it is one that we have been asked about by readers and also OEMs - using Adobe's Lightroom (or another application) to convert large raw images to JPEG.
For our testing we converted 100 15.1 Megapixel image files (just over 2GB of data) to the JPEG format (1280x853 resolution 72DPI) and timed how long it took to complete this. This test is a good real world test as more people take high resolution images and convert them for e-mail and the web.
Converting raw images to JPG takes CPU power and memory speed. The fact that AMD does not have that yet shows here. But, think about this; if AMD had the same memory performance as the 875 (roughly twice currently), it would come very close to beating that CPU at a much smaller price.
