Voodoo2 is the next generation of Voodoo Graphics. It is a
full- screen 3D-only solution that will use an external
pass-through cable to connect to your computer's existing video
card. Voodoo2 is designed for the serious game player who demands
the highest performance for games. In addition, two Voodoo2 cards
of the same type can be connected together to accelerate the next
generation of games.
Voodoo2 is an expandable architecture with a base
configuration of a 192-bit memory architecture and 2.2 Gigabytes
per second of memory bandwidth, delivering over 50 BOPS (Billions
of Operations per Second). This configuration delivers an
incredible 3 million triangles per second and 90 million
dual-textured, bilinear-filtered, per-pixel MIP-mapped,
alpha-blended, Z-buffered pixels per second, over three times the
performance of the current Voodoo Graphics.
