AMD said Wednesday that it continued to gain substantial increases in both desktop and mobile market share, owing to the success of its Ryzen CPUs.
Citing figures from Mercury Research, AMD said that its desktop unit market share grew about 10 points from a year ago, from 26.9 percent to 36.4 percent in the fourth quarter of 2025. In mobile, the gains were less pronounced but still significant, as its share increased from 23.8 percent to 26.0 percent, pushing past the traditional 80-20 split separating itself from its main rival, Intel.
AMD’s share has continued to increase steadily, seemingly producing a string of substantial increases in its market share when compared year over year.
In revenue share, AMD also made gains. Desktop revenue share increased from 28.0 percent a year ago to 42.6 percent for the fourth quarter of 2025. Mobile showed more modest gains, however: 21.6 percent to 24.9 percent.
AMD has soared in part due to the high regard paid its Ryzen 9000 and 9000X3D desktop processors, whose performance has substantially outperformed Intel. However, the company has also shipped a competitive Ryzen AI 300 notebook processor which has managed to outperform the competition in CPU benchmarks, helping elevate its market share.
AMD representatives were proudest of their increase in the server market to a record 41.3 percent revenue share, growing unit share slightly from 25.7 percent to 28.8 percent.
“These meaningful share gains across every major compute segment underscore strong execution and customer confidence in AMD’s leadership products across the data center and client businesses,” an AMD representative said in an email.
Mercury Research founder and president Dean McCarron said that a subset of his report would be released on Thursday, with the final, official figures inside.
