HD 7970 GHz Edition Review - Tahiti's Boost from Overclocking and Drivers
 

Today's review will focus on how the official increased clock frequencies of the 7970 GHz edition aka Tahiti XT2 - 1050MHz on the core (13.5% increase from 925MHz) and 1500MHz on the memory (9% increase from 1375MHz), help peg back or increase the performance delta over Nvidia's GTX 680 Kepler. We run a plethora of benchmarks on the latest beta drivers (Catalyst 12.7 and 304.48) from both camps, sometimes with interesting results to report.
