Performance

3DMark 2011

PowerColor’s dual-processor product comes out the winner of our first test. It enjoys an advantage of 23 to 32% over the GeForce GTX 580, depending on the graphics quality mode. It is also 95% ahead of the regular Radeon HD 6870, which proves the high efficiency of CrossFireX technology in 3DMark 2011. We should also note the strong performance of the SLI tandem built out of the two inexpensive GeForce GTX 560s. They take second place.

The PowerColor Radeon HD 6870X2 is even more impressively faster than the GeForce GTX 580 in this beautiful benchmark. The gap varies from 28 to 48%. The new dual-processor card is also twice as fast as the ordinary Radeon HD 6870. The two GeForce GTX 560s perform well in SLI mode, too. Considering that they are going to cost you $350-370 but beat the $500 GeForce GTX 580, that SLI configuration looks quite attractive.

BattleForge: Lost Souls

The PowerColor card beats the GeForce GTX 580 in BattleForge: Lost Souls, too. The gap varies from 13 to 35%, depending on the graphics quality mode. The Radeon HD 6870X2 looks good compared to the single-processor Radeon HD 6870 and adds 93-95% to the latter's speed. Take note that the efficiency of Nvidia's SLI technology is close to 100% here, so the SLI configuration beats the PowerColor card in the FSAA mode.

S.T.A.L.K.E.R.: Call of Pripyat

The Radeon HD 6870X2 is again ahead of the GeForce GTX 580 but the gap is smaller than in the three previous tests. CrossFireX technology is less efficient here than before, so the SLI configuration built out of two GeForce GTX 560s takes the lead. We seem to have assembled one very fast SLI tandem here.

Metro 2033: The Last Refuge

The Radeon HD 6870X2 might be praised for competing with the more expensive GeForce GTX 580 in Metro 2033: The Last Refuge if it didn't have such a low bottom speed. The two SLI-linked GeForce GTX 560s do not have such a problem and have a higher bottom speed compared to the single GTX 560.
