Asus GTX590 and HD6990 review

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 are measuring power consumption today in a slightly different way, by measuring the maximum drain taken when running 3dMark 11 at performance settings.

When idle, the GTX590 consumes around 13 watts more than the HD6990, under load we found that it could demand a maximum of 350 watts when compared against the HD6990's 323 watts.
