At Intel’s Developer Forum, Chief Technology Officer Justin Ruttner demonstrated one of Intel’s latest research items — a microprocessor that consumes insanely low levels of power.
Code-named Claremont, the circuits on this processor operate very close to their “threshold voltage,” which is the minimum voltage at which the circuit can change states and pass a current. This allows the entire processor to run on less than 10 milliwatts at its minimum, which is a significant improvement.
