SiS661GX implements a well-designed format that enables P4 Front-Side-Bus, DDR RAM and AGP 8X to achieve the optimal performance. The powerful chipset also provides superior image qualities that totally redefine the top-of-the-line graphic standard of the integrated chipsets.

Moreover, by adopting SiS's revolutionary HyperStreaming™ Technology and the intellectual data-processing module, SiS661GX offers the best performance for the Intel® platform and the most efficient resource distribution. The data transmission can be processed either synchronously or by batch to fully exploit the incomparable power of the Intel® processor.

SiS661GX supports the latest 533MHz Front Side Bus clock, proving a 3.2GB/s transferring bandwidth, stable high-speed computing function and multiple RAM formats such DDR400/333/266. Immerging SiS' Ultra-AGPII™ Technology and the outstanding graphic core, SiS661GX is able to achieve a VGA Throughput of 3.2GB/s with DDR400, significantly transcending the former 2.1GB/s standard speed provided by AGP 8X. SiS661GX's superb ECLK and 1600x1200 high resolution can support UXGA TFT-LCD output and perfectly perform high quality images for 3D games.
