Benchmark: Power Consumption
We've previously stated that Radeon HD 7000-series cards have set a new benchmark with respect to power-draw for a given level of gaming performance, but some of that benefit is negated in factory-overclocked cards that draw more power in an effort to reach higher speeds.
Performance is up by about six per cent in Crysis 2, but to obtain that relatively-small increase, system-wide power consumption while gaming jumps by 18 per cent on Gigabyte's OC card and 21 per cent on PowerColor's PCS+.
