ATI Graphics Card Buyer's Guide 2006, Part II

Power Consumption

The power consumption of our test system ranged from 125 to 360 W. The Radeon X1300 Pro and X1600 Pro mark the low end in 2D mode at 125 watts. The X1900XTX cards represented the high end at 360 W in 3D mode. Overclockers can expect power consumption to rise by another one to three percent. The peak values represent the maximum power draw that can be expected, and were measured under full load.

Heat

Graphics cards using Radeon 1300 and 1600 GPUs do not offer a temperature display, so no figures are provided for them. As you can see, the Radeon X1800 XT and X1900 XTX cards produce the most heat, operating at more than 90 °C. The peak values represent the highest temperatures that are to be expected, and were measured under full load.
