AMD’s November 3, 2026 third-quarter release reports company revenue growth of 45% and Data Center growth of 97% year over year. Those are growth rates. A separate calculation answers how much of the company’s current revenue comes from Data Center.
Calculate the share from matching columns
The release’s Selected Corporate Data table gives quarterly revenue in millions of dollars. For the three months ended September 26, 2026, Data Center revenue is 8,546 and total net revenue is 13,377. Dividing 8,546 by 13,377 and multiplying by 100 gives approximately 63.9%.
The comparable 2025 quarter shows 4,341 for Data Center and 9,246 for the company. The same calculation gives approximately 47.0%. The share therefore increased by about 16.9 percentage points, calculated from the unrounded ratios. These are calculations from AMD’s reported table, not a separately reported performance metric.

Share and growth answer different questions
A share calculation divides one part by the whole during a single period. A growth calculation compares the same measure across two periods. Label the numerator and denominator before interpreting either percentage. A faster-growing segment can gain share even while other businesses continue to contribute substantial revenue.
Avoid averaging business growth percentages without their starting revenue amounts. A small operation doubling and a large operation growing slowly will not usually produce the simple average of their growth rates. The starting weights determine the company result.
Try a fictional two-business example
Imagine a fictional supplier with two businesses, each beginning with 50 units of revenue. In the next period, Business A rises to 100 while Business B stays at 50. Company revenue increases from 100 to 150: growth of 50%. Business A grows by 100%, but its share of the new company total is 100 divided by 150, or about 66.7%.
Now change the starting mix: A begins at 10 and B at 90. If A doubles and B stays unchanged, company revenue rises only from 100 to 110. The growth rate of A is still 100%, but company growth is 10% and A’s new share is about 18.2%. The same segment growth rate produces a different company result because the starting weights changed.
This exercise uses invented units, not AMD business figures. It illustrates why a headline percentage needs a named measure, period and denominator.
Keep a reproducible reading note
- Copy the period and units with the figures.
- Use a segment and company total from the same quarterly column.
- Calculate each period’s share before subtracting them.
- Retain unrounded ratios until the final display.
- Label a change between shares in percentage points.
A revenue-mix calculation describes sales composition. It does not by itself measure profit, cash generation, unit shipments or a stock’s value.
