RIVA 128™
128-BIT 3D MULTIMEDIA ACCELERATOR
DESCRIPTION
The RIVA 128™ is the first 128-bit 3D Multimedia
Accelerator to offer unparalleled 2D and 3D perfor-
mance, meeting all the requirements of the main-
stream PC graphics market and Microsoft’s
PC’97. The RIVA 128 introduces the most ad-
vanced Direct3D™ acceleration solution and also
delivers leadership VGA, 2D and Video perfor-
mance, enabling a range of applications from 3D
games through to DVD, Intercast™ and video con-
ferencing.
