Lisa Su — The Quiet Genius Who Saved AMD

When Su became AMD CEO in 2014, the company's stock was $2. By 2024, it was $180 — a 9,000% increase. She turned a company that Wall Street left for dead into NVIDIA's primary competitor in the AI chip race, with a $250 billion market cap. She's one of the highest-paid CEOs in the S&P 500 ($30 million+/year) and the only woman running a major semiconductor company. She doesn't tweet memes or wear leather jackets. She just ships chips that work. In a list full of showmen, Su is proof that quiet competence can be its own form of celebrity — when the stock chart is the billboard.
