Voodoo Banshee features
Voodoo Banshee is the first of 3Dfx's family of integrated 2D/3D accelerators to storm into the consumer PC arena to score a one-punch knockout. The ultimate bridge between 3D entertainment and PC graphics is now available with unprecedented Voodoo2 3D technology. The Voodoo architecture, which has built a religious following among game developers, is now married with ultra-fast 2D, designed to accelerate graphic intensive Windows applications. Targeted for the demanding OEM, Voodoo Banshee complements 3Dfx's successful Voodoo2, the performance leader for 3D gaming. Best of class 2D and 3D performance from a single chip is now possible because Voodoo Banshee has it all!
