The Best Thing That Could Happen To Intel's Pentium 4 - The SiS645 Chipset

Quake 3 Arena

In Quake 3 Arena, SiS645 with DDR333 is pretty much able to reach i850 scores, while with DDR266 it is slightly faster than VIA's Apollo P4X266 chipset.

The same is valid for the NV15-demo, only that SiS645 is even able to beat i850 by a tiny amount.
