Digitimes is reporting that domestic pure graphics card makers could be in for a profitable quarter, while a shortage of GPUs from ATI could be a problem (still).[DigiTimes]Due to an IC substrate shortage, supplies of ATI’s Radeon 9250, X300, and X550 are short of demand at present, according to sources at graphics card makers. Although the chip vendor launched its 90nm process R5xx series only in the latter half of this year, the Radeon X1800, X1600, and X1300 are also limited in supply, the sources added.
