AMD reported second-quarter revenue of $11,536 million, up 50% from $7,685 million a year earlier, and the biggest reason sits in one line of the income statement: data centers [1]. GAAP net income reached $2,297 million, up 163% from $872 million, and diluted earnings per share came in at $1.38 versus $0.54.
The Data Center segment, which sells the accelerators and processors that run AI workloads, brought in $6,718 million, up 107% from $3,240 million. That single segment now accounts for 58% of everything AMD sells. Chief Executive Lisa Su tied the quarter directly to that business. "We delivered an excellent quarter, with record revenue and profitability as Data Center revenue more than doubled year-over-year," she said.
Profitability moved with volume. Gross margin rose to 54% from 40% a year earlier, and operating income was $1,990 million, a swing from an operating loss in the same quarter of 2025. AMD's release expressed that swing as a percentage off a negative base, a figure that overstates the change and is left out here in favor of the dollar amounts.
Chief Financial Officer Jean Hu framed the top line plainly. "Revenue increased 50% year-over-year to a record $11.5 billion," she said.
The throughline is concentration. More than half of AMD's revenue now depends on a data-center segment whose customers are a small set of cloud operators and AI developers. That concentration is the source of the record and also the risk in it: if AI capital spending cools, the line that carried this quarter is the line that would fall first. The same buildout that produced $6,718 million in data-center sales is the buildout now pressing on power grids from Texas to Virginia, a cost borne by ratepayers who are not on AMD's customer list.
