The AGP cards with NVidia's RIVA128 are just about a little bit faster than the two 3Dfx Voodoo cards, but also with worse image quality. However the RIVA drivers are still in alpha state, so that the quality as well as the performance will most likely improve in the future. Note the significant difference between the RIVA AGP cards and the RIVA PCI cards. The AGP cards with RIVA 128 chip are 20-25% faster than the PCI versions, which I consider as quite surprising.

The Quake II benchmark shows pretty much the same picture as above, only that the difference between RIVA AGP and PCI cards is even larger. The Videologic Apocalypse 3Dx (identical to the Matrox M3D) falls a bit behind here, compared to the GLQuake test and the Stealth II S220 is almost doing as well as the Apocalypse 3Dx.

The picture changes considerably when using a weaker CPU for 3D. Now the 3Dfx Voodoo cards are the clear champions and the RIVA cards are falling behind. Note that also here the RIVA AGP cards are still considerably faster than the PCI versions. The cards with 3Dfx Voodoo Rush chip are catching up with the Power VR chip, which proves again that the power of the 3Dfx Glide engine hardly decreases with decreasing CPU power. The Permedia 2 as well as the Verite 2100 don't seem to be too impressed about the slower CPU. Power VR and RIVA show a definite impact.

Again pretty much the same picture, only the Verite 2100 seems to favor Quake II, leaving behind an impressive number of cards and catching up with the Voodoo Rush cards.
