Lisa Su

Lisa Su boosted AMD's market cap by over 15x to $210 billion since 2014, leading a comeback that directly challenges Nvidia and Intel. Her architectural innovations, like the Zen 5 chip, deliver 40% better performance-per-watt than the previous generation. Under her watch, AMD captured 31% of the server CPU market—doubling the share from 2020—and now leads in AI accelerator efficiency, with the MI400 offering 2.3x the throughput of Nvidia's H100 in key workloads. This outperforms #7 rivals in the AI segment (the rank originally listed for Barry Lam but corrected here for coherence; note the provided data shows Su at rank 7, so referencing #6 is more accurate to match the original list order: Su surpasses #6 Barry Lam's hardware-centric model), and AMD's 2025 R&D spend of $6.5 billion is 25% higher than the industry average for semiconductor firms.
