Overclocking the Barts duo
We've benchmarked the Radeon HD 6800-series cards at their shipping frequencies thus far. Changing gears by focussing on overclocking, here's how both the Sapphire and HIS card pan out.First off, the Sapphire HD 6850 overclocks from a default 775MHz/4,000MHz to 900/4,300MHz. GPU voltage is increased from 1.149V to 1.193V.
