SiS GPU supports AGP8X, DirectX8.1

Claimed to be the world's first GPU to support AGP8X and DirectX 8.1 functions, the Xabre400 from Silicon Integrated Systems (SiS) Corp. provides a bandwidth of 2.1GHz—twice that of previous GPUs that supported the AGP4X bus.

This creates a "Balance PC" framework that allows data to flow freely between peripheral devices without suffering data transfer bottlenecks.

The GPU also supports the DirectX 8.1 specification and has a built-in Pixilizer engine that renders 3D images by enhancing the contrast of surface texture and improving surface mapping.

"The core and memory of the Xabre400 clock is at 250MHz and 500MHz DDR, showing that SiS has entered the high-speed GPU club," says Thomas Tsui, Director of the Multimedia Products Division. The chip also integrates the proprietary Frictionless Memory Control technology for more efficient memory and bandwidth use.

The Xabre400 also features jitter free anti-aliasing, Coloredeemer, and MotionFixing features to provide better color reproduction and life-like color images with higher texture detail, and color saturation and brightness.
