Radeon 7970 Overclocked vs GTX 580 Overclocked vs 6970 Overclocked
When AMD announced the Radeon HD 7970 last month they allowed reviewers across the globe to publish findings on the reference design card but not models from their partner manufacturers. In the run up to today, January 9th, it seemed like those manufacturers would launch with reference design cards only but then we received word from XFX that they would be releasing a 7970 with custom cooling and enhanced specifications.
With the only "launch day" 7970 that features an enhanced cooler and factory overclock in hand we decided to put it up against overclocked GTX 580 3GB and Radeon 6970 cards to see what the performance looked like… when each is overclocked to the fastest speeds available to buy, what performs best in the latest games such as Battlefield 3 and Skyrim? Let’s find out with some real world gaming on Intel i7/X79 @ 5.0GHz.
