AMD's Data Center Business Nears Two-Thirds of Sales as Gaming Revenue Falls 40%

Advanced Micro Devices is increasingly a data center company. Its third-quarter 2026 results, released November 3, showed nearly twice as much data center revenue as a year earlier, while the smaller gaming business contracted sharply. The contrast explains why AMD's newest outlook is being watched as a test of how quickly artificial intelligence infrastructure spending is reshaping the chipmaker.

Data centers now account for nearly 64% of AMD sales

AMD reported quarterly revenue of $13.377 billion, up 45% from $9.246 billion a year earlier. Its Data Center segment generated a record $8.5 billion, an increase of 97% year over year. Using AMD's reported rounded segment revenue against total company revenue, the segment represented about 64% of sales. This is a calculated share, not a separately disclosed growth rate.

The Data Center segment includes both EPYC server processors and Instinct accelerators. AMD attributed the segment's expansion to demand for EPYC CPUs and the launch of its Instinct MI450 GPU series. The full $8.5 billion should therefore not be described as GPU-only or AI-only sales.

Gaming moved in the opposite direction

Gaming revenue was $773 million, down 40% year over year, which AMD attributed to lower semi-custom and graphics revenue. Its broader Client and Gaming segment brought in $3.7 billion, down 8%, but that combined figure masks different trends: Client revenue increased 7% to $2.9 billion while Gaming fell.

The diverging results do not establish that demand for AI chips directly caused the decline in gaming products. They do show where reported revenue growth is concentrated as AMD expands its data center systems and processor portfolio.

The next quarter is expected to be larger still

AMD forecast approximately $17 billion in fourth-quarter 2026 revenue, plus or minus 3%. The midpoint implies about 27% sequential growth and 66% year-over-year growth, according to the company's release. AMD also forecast a non-GAAP gross margin of approximately 55% for that quarter. These figures are management guidance, not realized results.

For the third quarter, AMD reported GAAP net income of $2.428 billion and diluted GAAP earnings per share of $1.46. On its separately defined non-GAAP basis, net income was $3.471 billion and diluted earnings per share were $2.09. These measures should not be interchanged or read as if the adjustments were immaterial.

Independent reporting by Reuters on November 3 said AMD's $17 billion fourth-quarter sales forecast exceeded a $16.23 billion analyst average compiled by LSEG. Such comparisons depend on the estimate set and its timestamp; the published company forecast remains the primary figure.

Why this matters to S&P 500 investors

AMD is a constituent of the S&P 500's Information Technology sector. Its results offer a direct, company-specific view of the spending cycle in data center computing, an important theme among several large index members. The figures support the observation that AMD's business mix is moving toward server and accelerator infrastructure, but they do not prove that the broader AI investment cycle will earn adequate returns or predict an index-level price move.

The next useful checkpoints are actual fourth-quarter sales versus AMD's guidance, the balance of CPU and accelerator demand, non-GAAP versus GAAP profitability, and whether growth can persist amid supply constraints and fierce competition. As of this report, fourth-quarter 2026 performance remains a forecast.

Reporting basis and sources: AMD's fiscal third quarter ended September 26, 2026; the company reported results on November 3, 2026. Segment figures, GAAP/non-GAAP earnings and fourth-quarter guidance come from AMD's earnings release and the related SEC-filed exhibit. The analyst-consensus comparison comes from Reuters' November 3 report.
