Intel's CEO Brian Krzanic participated in Reddit's Ask Me Anything (AMA) session. One of the questions was "how does the development of Graphene change the game for Intel?"
Here's Brian's answer: "Graphene, carbon nano tubes.. and other 3-5 materials will become very important to semiconductors over the next few years... they will allow us to lower leakage and power while reducing geometries."
Back in September 2013, Brian said that Intel is working on graphene technologies, and are seeing some great progress. But graphene is still "a few generations away" from commercialization. In the best case scenario Intel sees graphene based products emerging in 2019, but that is rather optimistic.
