The big-beastie Sapphire Radeon HD 4850 X2 pulls the most watts, but the ATI Radeon HD 4890s - all three of them, Sapphire's included - are pretty similar. What's disappointing is that, from our testing at least, idle power-draw is significantly higher than NVIDIA GeForce GTX 275's.

Temperatures, though, are much better than on the ATI Radeon HD 4870.
