Lisa Su

Lisa Su, 53, is entering her 10th year as chair and CEO of the legendary Silicon Valley chipmaker AMD, which she is widely credited with rescuing. Su moved from Taiwan to the U.S. at the age of 3, eventually earning her engineering stripes at Bell Communications and IBM, where she founded and led the emerging products unit. Su turned the previously floundering AMD into a formidable presence in both the central-processing and graphics-processing markets. She's now trying to seize a significant chunk of the booming market for AI chips, which is currently dominated by long-standing graphics rival Nvidia. It won’t be easy, but Su wants AMD to become the industry leader in the next phase of AI’s development. AMD’s $49 billion acquisition of chip firm Xilinx last year is boosting those ambitions, as are improvements to the software that AMD needs to persuade developers to build their AI models on its systems.
