AMD Radeon HD 7970 Overclocking Performance Review

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.

Evaluation Method

We evaluate what each video card configuration can supply us in terms of a playable gaming experience while supplying the best culmination of resolution and "eye candy" graphical settings. We focus on quality and immersion of the gameplay experience rather than how many frames per second the card can get in a canned benchmark or prerecorded timedemo situation that often do not represent real gameplay like you would experience at home. Then we will follow with apples-to-apples testing in with minimum, maximum, and average framerates.

Test System Setup

We will be using a ASUS P8P67 WS Revolution motherboard, an Intel Core i7 2600K Overclocked at 4.8GHz, and 8GB of Corsair RAM.

Drivers

For the Galaxy MDT GTX 580 we used ForceWare 290.36.

For all AMD GPU based video cards we used AMD supplied driver for testing Radeon HD 7970 called "AMD_Radeon_HD_7900_Win7_64_Dec16.exe." The exact driver package version is shown above.
