Advanced Micro Devices Inc (AMD) just delivered a quarter that makes the AI narrative feel less like hype and more like a freight train. The chipmaker reported first-quarter results after Tuesday's close that blew past Wall Street's expectations, powered by what CEO Lisa Su called "accelerating demand for AI infrastructure."

Revenue came in at $10.25 billion, topping the $9.89 billion analysts were looking for. Adjusted earnings landed at $1.37 per share, beating the $1.29 consensus. That's a 38% revenue jump from a year ago, and the growth is coming from exactly where investors want to see it.

The Data Center segment, which includes AMD's AI accelerators and server chips, brought in $5.8 billion — up 57% year-over-year. That's now the biggest piece of AMD's business and the main engine of its earnings growth. Client and Gaming added $3.6 billion (up 23%), while Embedded contributed $873 million (up 6%).

"We are seeing strong momentum as inferencing and agentic AI drive increasing demand for high-performance CPUs and accelerators," Su said in the earnings release. "Looking ahead, we expect server growth to accelerate meaningfully as we scale supply to meet demand."

AMD generated $2.5 billion in operating income for the quarter and ended with about $5.59 billion in cash. The balance sheet looks solid, but the real story is the outlook.

For the second quarter, AMD expects revenue of approximately $11.2 billion, plus or minus $300 million. That's well above the $10.52 billion analysts had penciled in. The company also sees adjusted gross margin improving to about 56%, up from 55% in Q1.

Investors liked what they heard. AMD shares, already up about 66% year-to-date heading into the print, rose another 6.27% in after-hours trading to $377.53.

AMD executives will discuss the quarter in more detail on an earnings call at 5 p.m. ET. Given the numbers, it's likely to be a cheerful conversation.
