IBM has just introduced the world’s first integrated circuit, that is made of carbon allotrope graphene. CAG is a semiconductor that could push clock speeds much further than the traditional silicon-based wafers. Graphene has a microscopic crystal structure that allows processors to use smaller processes than silicon technology, allowing extremely large advances in processor clock speeds.
A jump like this would be like going from a megabyte to a gigabyte. IBM has currently demonstrated graphene-based transistors running at 100GHz, two and a half times faster than the current 40GHz (state-of-the-art transistors).
