NVIDIA’s newest Pascal generation came to all of us with unexpectedly high performance and improved energy efficiency but there was a significant drawback in the entire picture – due to the use of the so-called High Bandwidth Bridge, the new GeForce GTX 1080 and GTX 1070 video cards cannot work in 3-way or 4-way SLI modes. Or can they?
It turns out they can – after experiments by NVIDIA the GPU maker has announced that the GTX 1080 and GTX 1070 will work in 3-way and 4-way SLI modes but only a handful of applications, selected by NVIDIA, will be able to take advantage of computers with more than two Pascal GPUs. The list of programs has not been finished just yet but the popular benchmark programs Unigine Heaven, Catzilla and 3DMark Firestrike will work for sure. NVIDIA is likely to expand this list with more titles down the road but we will have to wait for a while.
Unfortunately games are not on the list and 3-way and 4-way SLI support lies with game developers so let’s hope that more and more game studios will optimize games for more than three Pascal GPUs in the near future.
