IBM Overclocks chip to 500Ghz at -269°C
@ 2006/06/20At room temperature, the IBM-Georgia Tech chip operates at 350GHz, or 350 billion cycles per second. That's far faster than standard PC processors today, which range from 3.8GHz to 1.8GHz. But SiGe chips can gain additional performance in colder temperatures.
"the research into higher-speed silicon-germanium chips will "enable a new generation of high-performance, energy efficient microprocessors."
Another hail the gigahertz round?
