AMD CPU Market Share Growth: Ryzen Desktop Dominates Q4 2025 with 36.4% Unit Share and 42.6% Revenue Share

In the fourth quarter of 2025, AMD achieved remarkable success, recording the highest CPU revenue and unit market share across both its EPYC and Ryzen product lines.

The latest analysis from Mercury Research indicates that AMD’s CPU market share has been on a steady rise. By the end of 2025, the company achieved its highest figures historically for CPU units and revenue. This article explores the details, starting with the client market.

During Q4 2025, AMD’s desktop revenue share surged by an impressive 14.6 percentage points year-over-year, and by 1.6 points since the previous quarter. Currently, AMD commands a desktop CPU unit share of 36.4% and a revenue share of 42.6%, marking the highest levels since the introduction of the Ryzen platform. The Ryzen CPUs, particularly the X3D series, are recognized as premier gaming processors, with models such as 7800X3D, 9800X3D, and 9850X3D highlighting AMD’s competitive prowess. Even older AM4 CPUs are gaining traction, influenced by the rising prices of RAM.

Similar to the desktop segment, AMD’s mobile CPU division also experienced a year-over-year increase of 3.3 percentage points. Presently, the mobile segment boasts a unit share of 26.0% and a revenue share of 24.9%.The Ryzen product lineup includes a wide range of options, from entry-level solutions to high-end Ryzen AI MAX series processors. With the ongoing rollout of the Ryzen AI 400 and AI MAX series, we anticipate continued growth in this segment. Notably, AMD has effectively positioned its Ryzen AI chips against Intel’s latest Panther Lake “Core Ultra Series 3″offerings.

Turning to the server market, AMD’s EPYC segment achieved a revenue share increase of 4.9 percentage points year-over-year, along with a 1.8 point quarterly increase, resulting in a current share of 41.3%.The server unit share stands at 28.8%, nearing the 30% milestone. AMD’s Genoa and Turin CPUs predominantly drive this growth, while older models continue to see strong demand. Moreover, AMD plans to launch its next-generation Venice CPUs based on the Zen 6 architecture later this year, which are set to enhance its offerings alongside the new Instinct MI450 series accelerators.

Server revenue share up 4.9 percentage points Y/Y and 1.8 percentage points Q/Q to 41.3%.
Client revenue share up 7.4 percentage points Y/Y and 3.0 percentage points Q/Q to 31.2%.
Desktop revenue share up 14.6 percentage points Y/Y and 1.6 percentage points Q/Q to 42.6%.
Notebook revenue share up 3.3 percentage points Y/Y and Q/Q to 24.9%.
Overall revenue share grew by 6.8% Y/Y and 2.9 percentage points Q/Q to 35.4%.
