Technical data / specifications
The ASUS EAH 6950 has been built according to AMDs reference design
which features a massive dual slot cooler and a back plate to cover and protect the cards PCB. From an architectural point of view the biggest changes have been made regarding the Shader units. For several generations AMD made use of 5D shaders. With the new Radeon HD 6950 and Radeon HD 6970 AMD implemented 4D shaders for the first time. The maximum theoretical performance inpact this could have is 20 percent. Furhtermore the HD 6950 is able to make use of a total of 1'440 shader units. If we look at the maximum board power, we see that compared to the Radeon HD 5850 the Radeon HD 6950 needs 30 Watts more on paper. In absolute numbers this means that the Radeon HD 6950 can draw a total of 200 Watt from the power supply. Regarding the idle power also the HD 6950 uses only 20 Watts which is industry leading at this time. New is, that AMD nowadays also provides a number regarding "typical gaming power". They claim that the card needs about 140 Watt on average when playing video games on your comptuer.
