Superconducting Microprocessors' Turns Out They're Ultra-Efficient

Long-time Slashdot reader AmiMoJo quotes IEEE Spectrum:Computers use a staggering amount of energy today. According to one recent estimate, data centers alone consume two percent of the world's electricity, a figure that's expected to climb to eight percent by the end of the decade. To buck that trend, though, perhaps the microprocessor, at the center of the computer universe, could be streamlined in entirely new ways. One group of researchers in Japan have taken this idea to the limit, creating a superconducting microprocessorone with zero electrical resistance. The new device, the first of its kind, is described in a study published last month in the IEEE Journal of Solid-State Circuits ... The price of entry for the niobium-based microprocessor is of course the cryogenics and the energy cost for cooling the system down to superconducting temperatures. "But even when taking this cooling overhead into account," says Christopher Ayala, an Associate Professor at the Institute of Advanced Sciences at Yokohama National University, in Japan, who helped develop the new microprocessor, "The AQFP is still about 80 times more energy-efficient when compared to the state-of-the-art semiconductor electronic device, [such as] 7-nm FinFET, available today."Read more of this story at Slashdot.
