Triple-GPU Scaling: AMD CrossFire Vs. Nvidia SLI

Benchmark Results: 3DMark 11

The latest 3DMark version is supposed to remove any Nvidia bias as a result of artificially-inflated PhysX results, so we see big problems for AMD if these results are repeated in games.

Performance for AMD and Nvidia becomes approximate at 3DMark 11’s Extreme preset, and the multi-GPU scaling appears solid with both brands. Let’s see how this works in the real world, where it counts most!

    wow even though a 6950 is weaker than a 570 it dominates at higher resolutions eyefinity here i come.

    Impressive and unexpected results. Speculations that crossfire scaling is worse than SLI can finally be put into rest.

    scrumworksImpressive and unexpected results. Speculations that crossfire scaling is worse than SLI can finally be put into rest.Not true, I would have liked to see more games on the test. The choices were too limited for my taste. For example, everyone knows that Crysis is heavily Nvidia favored, so it's not surprising to see those results in the least.

    Here's another article on the 68xx series in Xfire

    Xfire scaling was found to be 100% on 10 or the 19 games they tested, and remaining very high on the others. Nvidia and ATi seems to trade blows at different games tested, but it is evident that Ati has stepped up their Xfire drivers int he 6xxx series.

    Now im thinking if i should even spend on a now older 5850 to crossfire on my X58.

    Its really cool to see amd stepping up their game. Multigpu scaling used to be only good on nvidia, but now amd is beating them. Though i feel that more games should be tested before a firm conclusion should be drawn.

    I would get two HD 6870 for a mobile crossfirex gaming rig ! :D

    No! Don't buy a 5000-series card to crossfire. The 6000 series cards are essentially all better at crossfire scaling than their predecessors. This performance advantage will likely only increase with additional driver revisions and better 6000-series optimization support than for older products.

    Great review ! It's good to see AMD did a lot of work on CF scaling.
