IBM reseachers have made a breakthrough in the development of ultra-high-speed transistor design, creating a 100GHz graphene-based wafer-scale device. And that's just for starters.

The transistor that the researchers have developed is a relatively large one, with a gate length of 240 nanometers - speeds should increase as the gate length shrinks.

The field-effect transistor that the IBM team developed exploits what a paper published in the journal Science understates as the "very high carrier mobilities" of graphene, a one-atom-thick sheet of carbon atoms grown on a silicon substrate.

This extraordinarily thin sheet is grown on the silicon epitaxially, meaning that it's created in an ordered crystaline structure on top of another crystaline structure - in this case, good ol' garden-variety silicon. The graphene sheet has a hexagonal, honeycombed structure.

Wow, this is amazingly fast. I wonder when a TeraHz CPU will come out.

let them get the 100ghz ones out first,
at them speeds we could go back to single core hell half core

though what it would lead to is the interesting part 50ghz GPU's a legitimate need for insane speed components.
theoretically that could lead to about a 20ghz cpu in a mobile/cell
