Chinese team builds optical chip AI that is 100 times faster than Nvidia’s market leader

Chinese scientists have unveiled an optical computing chip that outperformed Nvidia’s leading AI hardware by over a hundredfold in speed and energy efficiency – particularly for generative tasks such as video production and image synthesis. The LightGen chip was developed by a team from Shanghai Jiao Tong University and Tsinghua University, harnessing the speed of light to execute complex artificial intelligence workloads. With more than 2 million photonic neurons integrated into a compact chip,...
