Researchers built a switch 1,000 times faster than today's AI chips, and it barely generates any heat
Science Hardware research magnetic Researchers built a switch 1,000 times faster than today's AI chips, and it barely generates any heat University of Tokyo's antiferromagnetic spintronic switch operates at picosecond speeds By Kishalaya Kundu May 17, 2026, 8:46 29 comments Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. The big picture: Researchers at the University of Tokyo have developed a magnetic switching device that can operate at speeds up to 1,000 times faster than the fastest AI accelerators on the market today, but uses only a fraction of the energy and generating minimal heat.
