Next-Gen Chips Will Be Powered From Below

Cars That Think

Had these chips kept on the trajectory they were following in the early 2000s, they would soon have packed about 6,400 watts onto each square centimeter—the power flux on the surface of the sun. that bad because engineers worked to hold down chip power consumption. We refer to this as front-side power delivery.
