[Para 2-3: Supporting details & Context] Looking ahead to Q1, AMD estimates revenue at $9.8 billion, plus or minus $300 million, exceeding market expectations of $9.38 billion.

AMD's stock has doubled over the past year. AMD recently announced significant client wins, including OpenAI and Oracle (ORCL-US). The company plans to ship its integrated, server-scale AI system, Helios, later this year. AMD CEO Lisa Su mentioned during the Q4 earnings call that the company is actively pursuing more Helios orders. Helios sales are categorized under AMD's Data Center department, which saw Q4 revenue of $5.4 billion, up 39% year-over-year. Growth is driven by both CPU and AI GPU sales. Su also noted that the AI boom is not only boosting GPU sales but also driving CPU sales. "Server CPU demand remains very strong. Hyperscalers are expanding their infrastructure to meet the growing demand for AI cloud services. Enterprises are upgrading their data centers to ensure they have the computational power required for new AI workflows." The client and gaming department saw revenue growth of 37% year-over-year, reaching $3.9 billion, primarily due to increased demand for Ryzen processors in notebooks and personal computers, expanding AMD's market share from Intel (INTC-US). In contrast, AMD's Embedded Systems department saw more modest growth of 3% year-over-year to $0.95 billion. Additionally, the market is watching AMD's ability to continue shipping AI chips to China under U.S. export controls. AMD reported Q4 sales of $390 million in China from Instinct MI308 chips, and expects Q1 revenue from China to be approximately $100 million.
