To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Crysis Warhead and record the results.
In such an energy aware climate, AMD are making a big deal out of their new ‘ZeroCore Power’ technology. Many solutions today use power gating, clock gating and memory compression to reduce idle power requirements, but ZeroCore power technology can completely power down the core GPU while the rest of the system remains active.
Both cards are very energy efficient, especially the HD7750 which takes all the power it needs from the PCI E slot. 43 watts when gaming is very impressive.
great looking cards. still a bit costly for what you get I think. Crossfire any better than it was a few years ago? nothing worked when I had two cards. (well worked the way it should have). That is why I moved to nvidia.
I wasnt impressed. but I can see the merit with two of them in Crosfire.
Have to ask. Would the people buying one of these really be able to afford two?
This is why crossfire makes sense. Obviously we have the rich guys who buy two high end boards to break benchmark scores, but back in the real world. you buy one, use it for a while, save up. then get another. you have high end card power for less money with less initial outlay.
First time ive seen a company sell a bundle, with two in it. with two free games those cards work out at £135. its not bad value considering.
