Future computers could use 1 million times less #energy, UC Berkeley researchers say

06 Jul 2011: Future Computers Could Use 1 Million Times Less Energy, Researchers Say Emerging computer technology that would use magnetic microprocessors instead of silicon-based chips has the potential to consume 1 million times less energy per operation than existing computers, according to an analysis by University of California, Berkeley researchers. Unlike existing microprocessor technology, which relies on electric currents that generate enormous amounts of wasted heat, the new technology, currently under development, would instead use closely packed magnetic chips to store and process information that would not require any moving electrons, the researchers say. According to their paper, published in the journal Physical Review Letters , such microprocessor chips have the potential to dissipate only 18 millielectron volts of energy per operation at room temperature —...
