Ivy Bridge E SLI Gaming Performance
Since Ivy Bridge E has 40 PCIe x16 lanes we would have missed a huge opportunity to not benchmark the processing using two high-end graphics cards. Since only high-end cards would saturate the limited lanes available to lower end chips in the Ivy Bridge series we turned to Nvidia to see if we could get our hands on another GTX 780. They agreed and history was made!
Metro Last Light:
With both Nvidia GeForce GTX 780 graphics cards running at x16/x16 they were really able to stretch their legs. In all of the benchmarks the performance boost from adding a second card was massive and it would be even bigger if we would have had a third GTX 780 on hand. When adding 3 or more graphics cards the bandwidth is going to start being split between the cards at less than x16, but the amount of bandwidth available to high-end graphics cards compared to a Haswell system is substantial.
