AMD CEO Lisa Su showed off a number of the company's AI chips on Monday (January 5) at the CES trade show in Las Vegas, including its advanced MI455 AI processors, which are components in the data center server racks that the company is selling to firms like ChatGPT maker OpenAI.

Su also unveiled the MI440X, a version of the MI400 series chip designed for on-premise use at businesses. The so-called enterprise version is designed to fit into infrastructure that is not specifically designed for AI clusters. The MI440X is a version of an earlier chip that the U.S. plans to use in a supercomputer.

AMD is one of Nvidia's strongest rivals but has struggled to have as much success. In October, AMD signed a deal with OpenAI that, in addition to the financial upside, was a major vote of confidence in AMD's AI chips and software. But it is unlikely to dent Nvidia's dominance, as the market leader continues to sell every AI chip it can make, analysts said.

At the Monday event, OpenAI President Greg Brockman joined Su on stage and said chip advancements were critical to OpenAI's vast computing needs.
