AMD's stock price plunged more than 10% after the market closed. AMD's data center revenue in the fourth quarter increased 69% year-on-year to $3.86 billion, but was lower than analysts' estimates of $4.09 billion, indicating that it has failed to narrow the gap with Nvidia in the field of artificial intelligence computing power. AMD expects total revenue in the current quarter to be between $6.8 billion and $7.4 billion, while analysts' average estimate is $7.04 billion. AMD's financial report has investors worried that the company's momentum in entering the field of AI computing power is weakening.
