Power Consumption

Here I have broken down our power consumption numbers into the same groups that the main article performance benchmarks were shown in.

AMD ATI Radeon HD 2600 XT, 2600 Pro and 2400 XT Review - Graphics Cards 189

AMD ATI Radeon HD 2600 XT, 2600 Pro and 2400 XT Review - Graphics Cards 190

First, looking at the Radeon HD 2600 XT, its load power consumption is the lowest of the first set, coming in about 10 watts lower than that of the 8600 GT card.  Once the SLI and CrossFire modes are tested, the load power used by the two 2600 XTs is about the same as the 8600 GTs but still about 30 watts less than the 8600 GTSs.

The 2600 Pro does use significantly less power than the the 2600 XT, but you can tell that in its gaming performance as well.  The 2400 XT card only draws 180 watts (full system) under load.  That is 37 watts less than the HD 2600 XT and 60 watts less than the 8600 GTS.  Even when paired up in CrossFire mode, the 2400 XTs only draw 201 watts of power; less than a single 8600 GT card.
