IBM's frozen chip has claimed (at least for now) the silicon-based chip speed record with it's 500GHz SiGe (silicon germanium) chip developed in concert with the Georgia Institute of Technology (GIT). The chip operated at 350GHz at room temperature and was able to achieve 500 GHz by cryogenically "freezing" the circuit to minus 451 degrees Fahrenheit (4.5 Kelvins).
