Sapphire HD7950 Vapor-X Edition 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 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.

The Sapphire HD7950 Vapor X Edition consumes more power than the reference HD7950 in the secondary ‘performance' bios position, indicated earlier by the PCB adoption of a single 6 pin and single 8 pin power connector.
