LAS VEGAS (Reuters) - Amazon.com's cloud unit on Tuesday showed new data center servers packed with its own AI chips that will challenge Nvidia ( NVDA ), with Apple ( AAPL ) coming aboard as a customer to use them.

The new servers, based on 64 of Amazon Web Services' Trainium2 chips, will be strung together in a massive supercomputer with hundreds of thousands of chips, with the help AI startup Anthropic, which will be the first to use it. Apple ( AAPL ) executive Benoit Dupin also said that Apple ( AAPL ) is using Trainium2 chips.

AWS Chief Executive Matt Garman also said that Trainium3, the company's next generation of AI chip, will debut next year.
