Conclusion
First of all lets talk about prices. Let's consider that
the two GTX 760 DirectCU II OC together cost 418 Euro. Compare that to the
563 Euro you'd have to pay for the cheapest reference GTX 780 Ti we can
find. Therefore this one high-end card is significantly more expensive than the
two mid-range models.
To dive a bit deeper into the results, we start with performance differences in
3DMark graphics score where we see that the SLI of two GTX 760 is 14 percent faster
than the GTX 780 Ti. In the next theoretical test we ran, Unigine Heaven,
we see that the two 760's are on average 14 percent quicker than the GTX 780 ti.
In case of games it turns out the for exampel in The Elder Scrolls: Skyrim the
GTX 780 Ti si about 3 percent quicker than the two smaller cards in SLI. A
closer look at Call of Duty: Black Ops 2 shows the other end of the scale, where
the two GTX 760 score 31 percent better than the single GTX 780 Ti. Overall it
is interesting to see that the GTX 780 Ti is quicker in highly demaning games.
Once again the reason lies within the amount of graphics memory, since the VRAM
of the two small cards is just too small for games with huge textures or
for ultra high resolutions.
Overall the two GTX 760 cards are performing really well and there is no doubt
the two of them are seriously quick. But in case of the particular models we tested, the graphics memory is
too small for the performance delivered, there will be the usual SLI issues,
although NVIDIA is taking quite good care of that and last but no least there is
the power consumption which is 43 percent higher than with one single GTX 780 Ti.
If you're actually thinking
about buying two GTX 760's make sure you go for models with 4 Gigabyte VRAM
otherwise the GTX 780
Ti will be quicker playing games at ultra high resolutions. When it
comes to price/performance, than the two GTX 760 in SLI are simply great. Since
drivers are meanwhile quite well optimized for SLI, almost any new game is
supported with well balanced profiles.
