Associates from the American site dailyTech get new information about the speed Of radeon HD 2900 XT, they published the brief testing results in games and professional graphic applications.
Thus, we start from some characteristics of video card radeon HD 2900 XT. It is equipped with 512 mb memory type GDDR- 3, that works at frequency 1650 MHz DDR and communicate with video chip on 512- bit system bus. The frequency of chip r600, as it was assumed is set to 750 MHz. The video card Length composes 9.5 inch, approximately 241 mm. this allow to install it in the majority of case . There are two additional power connector - eight and six-pin.
The video card cooler is similar to the one used in video card radeon HD 2600 XT with memory GDDR-4.
Actually the r600 chip can have 64 standardized shader processor, each of which contains one four-dimensional vector and one scalar blocks.
The tests Results below were obtained with the following configuration:
- Processor intel core 2 Extreme QX6700 (2.66 GHz);
- Motherboard intel D975XBX2 (i975X);
- 2 x 1 Gb memory type DDR 2-800;
- Operating system Windows XP;
- Drivers AMD catalyst 8.361 RC4 (for Radeon HD 2900 XT);
- Drivers forceWare 158.19 (for GeForce 8800 GTS 640 mb.).







Thus, the comparison Of radeon HD 2900 XT and GeForce 8800 GTS result on 28% average deference . We will not forget, that NVIDIA has already faster video card in comparison with GeForce 8800 GTS ( geForce 8800 GTX ) , and also the soon released card geForce 8800 Ultra.






The following comparison in professional graphic appears somewhat strange. The video card radeon HD 2900 XT is gaming product, and Quadro FX 5500 is based on chip from previous generation g71, although equipped with 1 Gb memory type GDDR- 3. Related Products :
