AMD has reached a major milestone in the CPU market. New data from Mercury Research shows that Q4 2025 was one of the strongest quarters in the company’s history, with AMD posting record results across desktop, mobile, and server segments.

The biggest highlight comes from desktop CPUs. In Q4 2025, AMD’s desktop revenue share climbed to 42.6%, which is the highest level the company has seen since the launch of Ryzen. Desktop unit share also continued to rise and now sits at 36.4%. This growth was driven largely by strong demand for Ryzen processors in both OEM systems and the DIY market.

X3D continues to be a massive boost for the desktop segment

AMD’s X3D lineup has played a key role here, as chips like the Ryzen 7 7800X3D, Ryzen 7 9800X3D, and the newer Ryzen 7 9850X3D remain some of the most popular gaming CPUs available. Even older AM4 processors are still selling well among DIY PC builders, partly because rising memory prices have made platform upgrades more expensive for buyers.

AMD also saw steady gains in the mobile CPU segment. Notebook processors recorded a year-over-year increase of 3.3 points in revenue share, reaching 24.9%, while unit share now stands at 26.0%. This growth comes from a broad Ryzen mobile lineup that covers entry-level systems, mainstream laptops, and high-end devices powered by Ryzen AI MAX chips.

On the server side, AMD delivered another strong quarter. EPYC processors reached a record 41.3% revenue share in Q4 2025, with unit share climbing to 28.8%. Demand remains strong for current Genoa and Turin CPUs, while older EPYC models are still shipping in large volumes. Only six months ago, we noticed AMD was quickly closing the gap towards a 50/50 split. More good news for AMD is its server CPUs are experiencing fewer delays; Intel is reportedly facing delays of up to 6 months in China.

When looking at the bigger picture, AMD’s overall CPU revenue share reached 35.4% in Q4 2025, up 6.8 points year over year. While the company has not yet crossed 40% in total CPU revenue across all segments, its desktop and server divisions clearly have.
