Loihi 2 packs 1 million neurons in a chip half the size of its predecessor

Many AIs may depend on things called neural networks, but there's very little about them that works in the way human and animal brains do. Intel has been experimenting with computers that think more like a brain does for several years now, racking up some impressive if quirky results with their Loihi neuromorphic chip. Now Loihi is getting its first upgrade, and it's a pretty big one. Using a manufacturing process called Intel 4 that's not yet available for commercial chips, the company packed in up to eight-times as many artificial neurons into a chip that's half the area of Loihi. That, and a host of changes motivated by the past few years of experiments, make the Loihi 2 faster and more flexible
