STORY: Advanced Micro Devices CEO Lisa Su took the stage in Las Vegas on Monday.
Speaking at the annual Consumer Electronics Show, she showcased the company's latest AI hardware and held up new chips for the crowd to see.
"MI455 is the most advanced chip we've ever built. It's pretty darn big. It has 320 billion transistors, 70% more than MI355."
These chips power data-center racks that AMD sells to firms like OpenAI.
The president of the ChatGPT-maker, Greg Brockman, joined Su on stage.
He said chip advances were vital to OpenAI's vast needs for computing power.
Su also had big claims for another platform:
"So let me tell you what it is. This is the smallest AI development system in the world, capable of running models with up to 200 billion parameters locally not connected to anything."
AMD remains Nvidia's top rival in AI chips, but trails in market share.
A recent deal with OpenAI has been seen as a show of confidence in the company.

But analysts say it's unlikely to dent the dominance of Nvidia, which showed off its own new chips the same day.
Boss Jensen Huang says they deliver a five-times boost in power for AI uses.
