The standings of the graphics cards in the first test correspond to their recommended pricing. The new Radeon HD 6930 is somewhat faster than the HD 6870 and 20% slower than the HD 6970. When overclocked, it gets closer to the HD 6970, the gap shrinking to 7-9%.
The overclocked Radeon HD 6930 is even closer to the HD 6970 in 3DMark 2011. The gap is a mere 2-4%. When clocked at its default frequencies, the HD 6930 is somewhat ahead of the Radeon HD 6870.
Unigine Heaven Demo
Working at 920/5720 MHz, the Radeon HD 6930 proves to be able to deliver the same performance as the Radeon HD 6970 at 880/5500 MHz which costs twice the money. We should also note that the Radeon HD 6930, when clocked at its default frequencies, delivers the same performance as the Radeon HD 6870. The latter’s higher GPU frequency helps it keep up with the newer card.
S.T.A.L.K.E.R.: Call of Pripyat
Working at its default clock rates, the Radeon HD 6930 is but barely ahead of the Radeon HD 6870 but can compete with the HD 6970 when overclocked. The HD 6970 is faster when we enable antialiasing, though.
Left 4 Dead 2
The graphics cards are all very fast in Left 4 Dead 2. The average frame rate is never lower than 130 fps. The standings are the same as in S.T.A.L.K.E.R.: Call of Pripyat, though.
Metro 2033: The Last Refuge
The game produced the same results irrespective of whether we enabled FSAA or not. Therefore we tested the graphics cards in the FSAA-less mode only.
As opposed to the previous game, the graphics cards deliver very low frame rates even though the game settings weren’t set at their maximums. The Radeon HD 6930 overtakes the HD 6970 when overclocked and is somewhat faster than the HD 6870 when left at default frequencies.
