Intel Core i7-4930K 3-way SLI Gaming Performance Scaling
Category : 2014
Published by Hiwa Pouri on 25.04.14
In our 3-way SLI gaming performance scaling articles we're going to investigate 3-way SLI scaling factors with different CPUs and different clock speeds. In eight recent games and two theoretical benchmarks we want to find out what difference 3-way SLI makes, when we run benchmarks with the CPU at stock clocks as well as overclocked to 4.5 GHz. Let's kick off with an Intel 4930K CPU and three ASUS GTX 780 DirectCU II graphics cards and find out what the differences are going to be like.

Conclusion
As we already mentioned, this article marks the start of a new series, and we're going to show you test results und 3-Way-SLI scaling. Comparing to our 2-Way-SLI articles the conclusion is going to be quite a bit shorter. The reason is, that only with theoretical benchmarks we find consistent scaling and in case of games, well, they're just not optimized for 3-Way-SLI. Apparently there are no rules without exceptions.
Referring to 3DMark we see that the overall socre is between factor 1.20 and
1.28 (depending on our CPU preset) higher than with one card. Translated into
the raw GPU score we see an scaling factor of maximum 1.39, which is usually about the
maximum scaling you get with 3-Way SLI. A closer look at Unigine Heaven reveals that
in case of the basic preset scaling factor is 1.06 at stock frequencies
and 1.05 with the CPU at 4.5 GHz. When it comes to the Extreme Preset then we
see that the GPU has much more influence again, which is acutally rather
obvious, since there is much higher load on the VGA(s). In this case scaling factor with standard clocks is 1.49 and with at 4.5 GHz we get 1.40.
Games on the other hand are a completely different story. Scaling factors at
low resolutions vary from 1 to 1.13. 1 basically means, the fps didn't change at
all and 1.13 marks a 13 percent increase in FPS. A 13 percent gain we measured using Crysis 3 and running the CPU at 4.5 GHz.
Now lets focus on high resolution and high details, where the games cause quite
some load on the two graphics cards. In this case the lowest scaling factor we
find is simply 1.00. In fact, most of the games fps rates don't scale with adding a third graphics card. There is only Call of Duty Black Ops 2 where we've measured a significant increase, which means, the performance went up by 36 percent (a factor of 1.36).
Putting more than two graphics cards into a gaming PC is basically not going to affect frames per second in most games. There are only very few titles where triple SLI is supported. The only reasonable thing to use triple SLI for is for breaking world records. Only when running theoretical benchmarks we come accross consistent scaling and with most of the games, there is no difference at all.
