According to 3Dmark 11 Pro, the Gigabyte HD 7970 SOC is 17% faster than a standard HD 7970 and 7% faster than the GHz Edition card. Without any voltage modifications, we were able to reach a core clock speed of 1.2GHz resulting in a score of 3362pts, 6% higher than Gigabyte’s factory overclock and 23% faster than the standard 7970.

Eventually, we arrived at a core clock of 1260MHz and 1600MHz for the GDDR5 memory which boosted the 3Dmark score to 3554fps -- 31% faster than the standard 7970 and quicker than both the previous-generation dual-GPU cards.
