Sapphire R9 280X Vapor-X OC and R9 290 Vapor-X OC 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 the synthetic stress test Furmark and record both results.

Both cards are clearly geared to demand a little more power – possibly to increase overclocking potential – more on this shortly however.
