To help paint a decent picture of the i810's OpenGL gaming performance I included some results using Quake II v3.20 using DEMO1.DM2, the famous CRUSHER.DM2 demo created by Brett "Three Fingers" Jacobs, and to provide an example of AGP performance S3's MON2.DM2 high texture demo.

Right off the bat you will notice that there are no SiS620 results plotted on the graph using the SiS620 integrated video. Why? Because the SiS620 chipset doesn't provide OpenGL drivers for Quake II. Because the SiS620 chipset was aimed at the low-end/low-cost market OpenGL gaming must not have been of great importance. However, I did include the ASUS SiS620 based platform configured with a V550 PCI board. The SiS620 based board configured with the V550 PCI was barely able to outperform the i810. The i810 performance looks pretty good for the average gamer. Single player Quake II is acceptable up to the resolution of 800x600. Definitely the best OpenGL performance I've ever seen in an integrated chipset. The visual quality of the i810 is also quite good, very similar to its older sibling the i740. The i810 integrated video couldn't match up to the TNT1. The i810 based DFI board with the V550 PCI board was able to outperform the i810's integrated video by 12FPS (frames per second). Another very interesting set of data points on this graph is the SOYO (i440ZX) and the DFI (i810), both configured with the V550 PCI. I find it very interesting that the DFI (i810) is able to outperform the SOYO (i440ZX) by at least 3FPS in each resolution. The DFI (i810) with the V550 PCI was almost able to achieve the high scores that SOYO was able to get with the V550 AGP configuration.
