DESCRIPTION

•

Adds 16Mbit SDRAM support for cost sensitive

8MByte framebuffer applications

The RIVA128ZX offers unparalleled 2D and 3D

performance, meeting all the requirements of the

mainstream PC graphics market and Microsoft’s

PC’97. RIVA128ZX combines all the features of

RIVA 128 plus 8MByte SDRAM and SGRAM

based framestore support and AGP 2X data trans-

fer. It provides the most advanced Direct3D ac-

celeration solution and delivers leadership VGA,

2D and Video performance, enabling a range of

applications from 3D games through to DVD, In-

tercast and video conferencing.
