OpenAI is racing to bring its own artificial intelligence chips into production, a move that could loosen Nvidia’s grip on the most valuable corner of the semiconductor market. By shifting part of its ...

Semiconductor chips that process light rather than electricity could boost processing speeds and reduce energy use.

Graphics processing units (GPUs), the chips on which most AI models run, are energy-hungry beasts. As a consequence of the accelerating incorporation of GPUs in data centers, AI will drive a 160% ...
