Another heavy blow into Nvidias face ? DigiTimes reports that Asustek, key customer for Nvidia?s graphics chipsets in Asia, expects to launch own-brand graphics cards featuring ATI solutions by the end of this quarter. The two sides expect to officially announce the news in late September, according to DigiTimes. Both Asustek and ATI denied the report. According to ATI, Asustek is producing some graphics cards featuring ATI solutions on request of its OEM clients, and is developing motherboards based on ATI?s 9100IGP chipset, but the two sides have not worked together in the own-brand graphics card market. It is still unclear whether Asustek would continue working with Nvidia in its own-brand graphics card business in the future, sources said.
