Q4 2025 turned out to be a fantastic quarter for AMD with the highest CPU revenue and unit share in both EPYC and Ryzen segments.
AMD x86 CPU Share Continues To Grow: Explosive Gains With Ryzen Desktop & Highest Share For EPYC
AMD's CPU market share has been growing steadily, and the end of 2025 saw its biggest CPU unit and revenue figures, as reported by Mercury Research. The latest figures show share increases in both client and server segments, so let's break down the numbers, starting with the client market.
In Q4 2025, AMD's Desktop Revenue share increased by 14.6 points (Y/Y) and 1.6 points versus the last quarter. Currently, AMD's Desktop CPU unit share sits at 36.4% while the revenue share sits at 42.6%, the highest they have been since the launch of the Ryzen platform. AMD's Desktop CPUs primarily consist of Ryzen offerings, which have been doing superbly across OEM and DIY segments. The company offers its Ryzen X3D chips as the fastest gaming solutions on the market, with the likes of 7800X3D, 9800X3D, and the most recent, 9850X3D, remaining unmatched. Even older AM4 CPUs are doing well due to rising RAM prices.
Just like the desktop side, the AMD Mobile CPU segment also saw a decent growth of 3.3 points year over year. Currently, the mobile segment holds a unit share of 26.0% and a revenue share of 24.9%. The company has a diverse portfolio of Ryzen chips in its stack with entry-level / refreshed solutions, the more current mainstream options, and the higher-end Ryzen AI MAX series. As the rollout of the latest Ryzen AI 400 and Ryzen AI MAX continues, we can expect this share to continue climbing upwards. AMD has also showcased how its Ryzen AI 400/300/MAX chips are positioned well with Intel's latest Panther Lake "Core Ultra Series 3" offerings.
Last but not least, we have the AMD EPYC or Server market share, which saw a revenue share increase of 4.9 points (Y/Y) and 1.8 points (Q/Q), leading to 41.3% share in the current quarter. The server unit share currently sits at 28.8%, fast approaching the 30% market share point. AMD's Genoa and Turin CPUs make up the volume of the lineup, and older chips are still being offered in vast quantities. Meanwhile, AMD's next-generation Venice CPUs based on the Zen 6 architecture are ready for launch later this year & will power the Helios racks with next-gen Instinct MI450 series accelerators.
- Server revenue share increased 4.9% points Y/Y and 1.8% points Q/Q to a record 41.3%.
- Client revenue share increased 7.4% points Y/Y and 3.0% points Q/Q to 31.2%.
- Desktop revenue share increased 14.6% points Y/Y and 1.6% points Q/Q to 42.6%.
- Notebook revenue share increased 3.3% points Y/Y and 3.3% points Q/Q to 24.9%.
- Overall revenue share increased 6.8% Y/Y and 2.9% points Q/Q to 35.4%.
