SiS Launches a Complete VIVO Graphics Chipset Solution Based on Conexant’s Multimedia Chipset
The Xabre600 Features New Input Capabilities and Provides A Whole New Visual Experience

Taipei, Taiwan, February 17, 2003 --- Silicon Integrated Systems Corp. (SiS), a leading supplier of core logic and graphics chipsets, announced a the first Xabre600 graphics chipset solution with VIVO functionality. Xabre600 incorporates the Bt835 multimedia chipset from Conexant Systems, Inc., which enables advanced video-in capability. SiS and Conexant worked jointly to develop this solution.

The Xabre600 is the first graphics card in the world to utilize AGP 8X. It supports the latest DirectX 8.1 hardware acceleration and delivers fast performance and realistic, highest-quality graphics. Integrating Conexant's Bt835 multimedia chipset, Xabre600 is able to provide a complete solution for analog video decoding and NTSC/PAL/SECAM signal inputs. Besides supporting multiple interfaces such as CRT-out, Video-out (S-video), and DVI, the new Video-in (S-video) and Composite Video-in ports offer unprecedented graphics with the Xabre600's advanced 3D engine. Users can exploit the full potential of Xabre600 by connecting PCs to game consoles, video recorders, and DV. It can also be used in combination with other application software for digital image editing to deliver crisp, high-quality images.

The SiS Xabre graphics chipsets are the first in the world to utilize AGP 8X. The new Xabre600 chipset offers an unmatched engine clock speed of 300MHz and memory clock speed of 300MHz. The revolutionary, innovative Vertexlizer(tm) Engine, a hardware optimized architecture, will dramatically enhance your visual experience.

About Xabre
In April 2002, SiS named its series of graphics chips "Xabre." The name Xabre comes from the word "saber” and is pronounced the same. A “saber” is a razor-sharp cavalry sword, which is fast wielding, precise, and sharp. The name Xabre exemplifies these qualities and the distinguished features of the chips, which are fast and make the virtual world of combat seem real to the users who run multimedia software and computer game applications.
