Fire Strike Standard and Extreme Results
Now we are starting to see some more interesting results and we can actually discuss the differences between hardware vendors. Starting with the high end, the Radeon HD 7970 CrossFire is running about 7% faster than our pair of GTX 680s in SLI while the single card results show a gap closer to 11.5%. While that means SLI is scaling better than CrossFire, it isn't enough to make up for the performance advantage of the AMD hardware.
While we didn't test every single current generation card, you can see how the various matchups work out. The GTX 660 Ti is slightly faster than the HD 7870 GHz Edition and the GTX 650 Ti is running a bit ahead of the HD 7770.
The graphics test and combined test frame rates pretty much mirror the scores above which you would expect considering they were all run on the same CPU and platform.
The Extreme preset, that runs at 2560×1440 with some higher image quality settings, wouldn't complete lower end GPU offerings but were able to run on the HD 7870/HD 7970 as well as the GTX 660 Ti/GTX 680. The relative performance didn't change though as AMD's HD 7970 again finds itself a bit ahead of the GeForce GTX 680 in both single and GPU configurations.
Again, a very similar result to the standard run (in terms of relative peformance differences) is seen when we look at the frame rates as well.
