Radeon HD 2900 GT
Under pressure from a competitor, ATI is forced to present a special simplified version of a video card from its flagship Radeon HD 2900 series. The 2900 GT model is based on a cut-down R300 graphics processor containing 240 rather than 320 shader units.
The video card is equipped with 256 MB of GDDR3 memory operating at 800 MHz, and the memory bus width has been reduced from 512 to 256 bits. Thus, the video card Radeon HD 2900 GT occupied an intermediate niche between the expensive HD 2900 series and the new "middle" HD 3800 series.
