The Ultra-AGPII™ technology is a high-level graphic mechanism specially developed by SiS for integration chipsets. It provides faster communication and greater transmission bandwidth between the built-in graphic engine and memory controller of the north-bridge chip.

The triggering of DDR400 will boost the VGA Throughput up to 3.2GB/s, a figure that is way above the standard 2.1GB/s of AGP 8X interface. The Ultra-AGPII™ technology provides the powerful efficiency required for 3D games and DVD operating and brings you the best image possible; moreover, it accurately renders the special graphics and light effect of PC games and videos.

Ultra-AGPII™ is a core graphic interface indispensable for both Notebooks and Desktop PCs.

Ultra-AGPII™ on SiS integration products ~ SiS661FX&SiSM661FX

With an embedded graphic engine and high-speed DDR400 function, both of SiS661FX/SiSM661FX employ the unique Ultra-AGPII TM technology and provide an excellent operating environment and outstanding display quality for heavy gamers and digital video players.

Immerging SiS' Ultra-AGPII™ Technology and the outstanding graphic core, SiS661FX 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. SiS661FX's superb ECLK and 1600x1200 high resolution can support UXGA TFT-LCD output and perfectly perform high quality images for 3D games.

Meanwhile, SiSM661FX also employs the unique Ultra-AGPII™ technology, which provides lower signal latency and offers greater transmission bandwidth between the built-in graphic engine and memory controller. By adopting the intellectual data-processing module, SiSM661FX ensures a better image quality. Moreover, the flexible dual-view application allows the screen to be simultaneously displayed on a CRT, TV or LCD monitor, and supports a maximum resolution of 1600x1200 in the full screen UXGA display. SiSM661FX presents superior added values to add to the overall benefits of the integrated chip set.
