IBM tests a 500 Ghz chip

IBM said it was able to achieve frequencies above 500 GHz by "cryogenically freezing" the chip.

Using liquid helium, they were able to cool the circuits to 451 degrees below zero Fahrenheit.

IBM said that silicon-germanium is likely to achieve even higher speeds, and may possibly to be able to reach 1 THz (1000 GHz) at room temperature.
