By Anhata Rooprai and Max A. CherneyAug 4 (Reuters) - AMD forecast quarterly revenue above Wall Street estimates on Tuesday, banking on strong demand for its chips from massive data-center capacity expansions to power AI technologies. AMD expects third-quarter revenue of about $13 billion, plus or minus $300 million, while analysts estimate $12.52 billion, according to data compiled by LSEG. The forecast ⁠suggests that AMD's investments to challenge Nvidia's dominance in the market for AI chips are beginning to pay off, with sales of its data-center processors accelerating in the second quarter. AMD's quarterly data-center revenue more than doubled to $6.72 billion, beating expectations of $6.48 billion. Second-quarter ​revenue ​jumped 50% to $11.54 billion, beating the estimate of $11.28 billion.
