IBM shows smallest, fastest 155GHz graphene processor

IBM demonstrated its fastest graphene transistor, which can execute 155 billion cycles per second, which is about 50% faster than previous experimental transistors shown by the company's researchers.

The transistor has a cut-off frequency of 155GHz, making it faster and more capable than the 100GHz graphene transistor shown by IBM in February last year, said Yu-Ming Lin, an IBM researcher.

What's more, the thing is also IBM's smallest to date, with a gate length of 40 nanometers; that's 200 nanometers less than the 100GHz iteration. This smaller, faster transistor was produced as part of a DARPA research project that aims to develop high-performance RF (radio frequency) transistors.

We won't be seeing these in our personal computer anytime soon but might be operating war machines of the future.
