3DMark
For our synthetic benchmarks we went with four different 3DMark tests, two each from 3DMark Vantage and 3DMark 11. The results from each program were consistent but in Vantage we saw the single 7970 outperforming two HD 6870’s in Crossfire but in 3DMark 11 it did not. Either way the only way we were able to beat the HD 7970 was pairing up two powerful cards in SLI or Crossfire, it is without a doubt a better performing single card than anything else we have tested.
