FUD Zilla received some information about the thermal numbers of ATI's Radeon HD 2900 graphics cards which will be launched next week:
According to a document we've seen the most powerful one is called the Radeon HD 2900 XT 1024MB DDR4. Its TDP, thermal design power of the GPU, is an astonishing 180 Watts, while the whole board dissipates 225 Watts.
The second card is the Radeon HD 2900 XT 512 MB GDDR3 and its GPU's TDP is 160W due to slightly lower clock speed and the whole board again dissipates 225 Watts.
The third and final card is the Radeon HD 2900 XL, a cheaper version of the architecture with 512 MB GDDR3 and its GPU will dissipate 130 Watts, while the board will dissipate 205 Watts.
Last week they already reported that the Radeon HD 2900 gets very hot, they published a picture of the card with a thermometer indicating a temperature of 82°C.
