3Dfx Voodoo 2 

The Voodoo² (V2) is 3Dfx's follow up to their critically acclaimed Voodoo Graphics chipset (VGC) and has been adopted by a number of major board vendors.

Just like the VGC these cards use a pass-thru cable solution where you hook up your 2D board to the V2 accelerator and then hook it up to your monitor. When a program makes a call to the V2 board it overrides the signal from the 2D card and then displays it's own full-screen image.

One of the limitations to the original VGC is still present in the V2, it can't render in a window hence it's useless for 3D applications like 3D Studio, Lightwave and AutoCAD that requires a simultaneous 2D display.

The V2 features dual texture management units (TMUs) for single-pass tri-linear filtering or light/bump-mapping. Running at 90Mhz (compared to 50Mhz for the VGC) the V2 performance up to three times faster than VGC based cards.
