XFX HD7870 Black Edition Overclocked Graphics Card Review

For the overclocking today, we are using Catalyst Control Center.

We managed to increase the core clock to 1,240mhz from 1,050mhz – translating to an 18 percent overclock. The memory maxed out at 1,345mhz (5380mhz effective).

The overclock increased the 3DMark 11 score from 6,797 points to 7,642 points, only 200 points behind the HD7970. Impressive results.
