Voodoo3 PCI Vs. AGP

I got a mail from 3dfx:
The Voodoo3 2000 comes in both PCI and AGP flavors, although the only
real
difference is in the fact that the AGP version will save you a PCI slot,
as
the Voodoo3 2000 does not take advantage of any advanced AGP features.
i hope it helps ;-)

more to AGP than just pulling textures out of system memory.
Consider my unofficial X1, X2 comparison!
AMD K-2 450, Ali Aladin V, V3 2K AGP
Q2, demo1.dm2, 800x600, default settings
X1 mode 48fps Doh!
X2 mode 86fps

Gotta disagree totally as far as the V3 is concerned.
Looks like you did not duplicate tests exactly, otherwise you would
have seen no difference.
My AMD K6-2 392 comparison.
FIC 503+ VIA MVP3 chipset.
64 meg.
V3 3000 AGP at 166mhz Vs. V3 2000 PCI at 144mhz
AGP bus at 75mhz, PCI bus at 37.5mhz
VIA AGP patch in 2X Turbo mode, and M/B bios at AGP 2X.
Q2 demo1.dm2, default settings.
800x600, V3-3000 AGP = 84.7 Vs. V3-2000 PCI = 83.1
1024x768 V3-3000 AGP = 75.9 Vs. V3-2000 PCI = 68.4
Unreal
800x600, V3-3000 AGP = 33.1 Vs. V3-2000 PCI = 34.7
1024x768 V3-3000 AGP = 29.9 Vs. V3-2000 PCI = 31.5
3DMark '99 Max 800x600:
V3 3000 AGP........... 3d = 2676.......... CPU = 5029
V3 2000 AGP............3d = 2674...........CPU = 5029
So strange as it sounds, it looks like the AGP slot adds
overhead that is not present in the PCI versions, which
would explain why the 2000 PCI actually was faster in Unreal.
Even without the speed benefit, the 3000 is a better deal if
you want the game pack and TV output, which works great.
