SLI vs. CrossFire, Part 2 – High-end multi-GPU scaling
Deus Ex: Human Revolution
Deus Ex Human Revolution is our latest benchmark. It uses the Unreal 3.5 engine with DX11 features including tessellation. Let’s test it at 1920×1200 and then at 2560×1600 with maxed details and with FXAA on high.
We see only fair CrossFire scaling and negative TriFire-X3 numbers. Nvidia has the advantage in this benchmark. Let’s check 5760×1080.
Again we see only fair scaling from CrossFire although TriFire finally gets marginally better frames than CrossFire. Again, the GTX 580 and GTX 580 SLI are the fastest solutions and they can easily play this game at 5760×1080 although the multi-GPU Radeons may have to have some details lowered.
Thanks for this article. It was a very interesting read
I’m really looking forward to the next parts in the series. Overclocking and potential CPU-bottlenecking in Single-Card VS SLI is something I’ve been wondering about for a long while. And also microstuttering, I’ve never experienced it myself, but it scares me enough to make me cautions of buying another GTX 570 to SLI.
And oh, is it possible to get Battlefield 3 Beta added in your test-games?
Thanks for the feedback. I would not be afraid of getting a second GTX 570 for SLI. Nvidia (and AMD) work to minimize micro stuttering in the drivers and it is something that you can generally further alleviate by backing down on settings if you notice it.
I plan to add BF3 to my regular benching suite after it is released. The beta is only going to be valid for less than a month.
Thank you very much for this! It isn’t easy finding benchmark results with newer drivers. Not for a quad-SLI or quadfire setup that is. Cheers!
Err, strike the quad-SLI and quadfire part, but all the same – it is nice to find more up to date benchmarks!
