3D Mark 2001
We can clearly see three different classes. The worst scores are of course generated by Intel's slow i845 chipset. The next level is shown by the two candidates with DDR266 memory, while SiS645 with DDR333 is able to reach i850 scores once more.
Vulpine GLMark
GLMark shows the same behavior as 3D Mark 2001. Again, SiS645 plus DDR333 reaches i850 scores.
