The HD 7970 is nice but not nice enough for Kyle and the gang over at [H]ard|OCP who started overclocking the card as soon as they polished off the review at default settings. If they were hoping for a challenge, the card was a bit of a disappointment as they cranked the overdrive frequencies to their maximums of 1125MHz GPU and 1575MHz RAM only to find that the card remained 100% stable. Discouraged but not defeated, they reached out to Sapphire for a custom version of the TRIXX Utility, which allows more control over voltages as well as significantly higher clock speeds. The resulting tests pegged the card at 1.26GHz GPU and 1725MHz for the memory, not too shabby for air cooling!
"We overclock the Radeon HD 7970 in Overdrive and show you what 1.125GHz of performance looks like. Then, we go to the edge and overclock the voltage and take this GPU past 1.2GHz for stellar overclocked gaming performance. We compare this to an overclocked GeForce GTX 580 and see how performance stacks up."
