Overview

Targeting on the consumer PC market in 1998, SiS6326 product series consisting of SiS6326, SiS6326AGP and SiS6326DVD provides high integration, super performance, and feature-rich 3D/2D graphics video accelerator and DVD playback compatibility. To meet sub-799 affordable PC requirement and target at 3D AGP 2X Gaming market, SiS6326AGP integrates AGP/PCI VGA controller, 3D/2D graphics accelerator and video accelerator with very competitive price. The 64 bit SiS6326AGP achieves an unprecedented 3D performance proven by the fill rate of 50 millions pixels per second with polygon rate of 2M polygons/sec @ 25 pixels/polygon. For feature-rich multimedia solution SiS6326 integrates not only the basic function but also NTSC/PAL TV-OUT solution, MPEG II video decoder, which brings more flexible and integrated solution for Customers. Derived from SiS6326, SiS6326DVD brings together full features all-in-one graphics and multimedia solution offering everything you need to find in your multimedia PC. With 80% of the video decoding (MC & IDCT) performed by MPEG-2 decoding architecture, SiS6326DVD provides full-motion DVD video at 30 frames per second under a standard Pentium MMX 233 platform. With macro vision-enabled architecture built-in, SiS6326DVD extends DVD entertainment experience through TV-monitor without any distortion. Similarly, high performance video accelerator brings flexible and various solution for video capture and video conferencing.

SiS 6326AGP features 8MB of powerful memory and presents leading edge 3D capability and exceptional acceleration performance. Advanced visual effects such as Gouraud shading, high quality dithering, tri-linear texture filtering and multiple texture blending are supported for the ultimate 3D gaming experience.

With an unbeatable cost/performance solution for PC OEMs and end users, SiS 6326AGP commit to delivering no-compromised graphics performance and continue to position itself a leader in the multimedia solution of mainstream PC market.
