Huh? The X850 Pro has 12 pipes; the X850XT has 16.
ATi's lineup was a lot murkier in the old days: 3D Rage II, II+, IIc,
IIc+PC2TV... Pro, Pro Turbo, XL... Then you add in the retail box names like
Mach64, 3DXpression, 3DCharger, Xpert98, 99, 2000...
I was looking for an old ATi card to play MechWarrior2, which used the 3DCIF
interface (basically ATi's Glide) and had a difficult time differentiating
the various cards.
