AMD HD7870 and HD7850 Graphics Card Review

To end the review today we thought it would be interesting to configure both cards in Crossfire.

We overclocked the HD7850 to from 860mhz to 1ghz core, so it matched the HD7870. Obviously this won't be quite as fast as a native HD7870 Crossfire configuration as the HD7850 has a lower shader count.

The mixed Crossfire performance is extremely impressive, slotting in a little behind the GTX 580 in SLi. Only 500 points behind in 3DMark 11 and 5 frames per second in Unigine Heaven.
