Google says its AI supercomputer is faster, greener than Nvidia

Alphabet Inc’s Google on Tuesday released new details about the supercomputers it uses to train its artificial intelligence models, saying the systems are both faster and more power-efficient than comparable systems from Nvidia Corp.

Google has designed its own custom chip called the Tensor Processing Unit, or TPU. It uses those chips for more than 90% of the company’s work on artificial intelligence training, the process of feeding data through models to make them useful at tasks like responding to queries with human-like text or generating images.
