The power consumption of our test system ranged from 126 to 385 watts. The Radeon X1300 marks the low end in 2D mode, drawing 126 watts; the 6800 GS SLI duo marked the high end, guzzling 385 W in 3D mode, with the Radeon X1900 XTX close on its heals with 360 W. Overclockers can expect power consumption to rise by another one to three percent. The peak values represent the maximum power draws that can be expected, and were measured under full load.

Graphics cards using the Radeon 1300 and 1600 GPUs do not offer a temperature display. 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.
