Intel’s Enduring Dominance in the x86 CPU Market

Intel has been the dominant supplier of x86 CPUs for decades. Despite AMD’s strongest gains in years, the latest Mercury Research data from Q3 2025 confirms that Intel continues to hold the majority position across desktops, laptops, and servers. This article provides a comprehensive look at the numbers, the structural reasons behind Intel’s lead, and the implications for the future of the CPU industry.

Overall Market Share

Mercury Research reports that AMD has crossed the 25 percent milestone in overall x86 CPU shipments. When semi-custom chips such as console processors are included, AMD’s share rises to 30.9 percent. Intel still controls between 69 and 75 percent of the market depending on whether semi-custom products are counted. This demonstrates that Intel remains the majority supplier of x86 processors worldwide.

Desktop CPUs

AMD has reached a record 33.6 percent share of the desktop CPU market. This is the highest level in the company’s history and reflects strong adoption of Ryzen processors among enthusiasts and mainstream users. Intel, however, continues to power 66.4 percent of desktop systems, maintaining its lead through broad OEM coverage and aggressive pricing in volume segments.

Mobile CPUs

In laptops, Intel’s dominance is even more pronounced. Mercury Research reports that Intel holds 78.1 percent of the mobile CPU market, compared to AMD’s 21.9 percent. Intel’s entrenched relationships with major OEMs, combined with its extensive portfolio of mobile processors, ensure that most thin and light notebooks and business machines continue to rely on Intel silicon.

Server CPUs

AMD’s EPYC processors have steadily gained traction in data centers, reaching 27.8 percent of the server CPU market. Intel still commands 72.2 percent, supported by decades of enterprise trust, ecosystem integration, and a wide range of Xeon SKUs. While AMD’s progress is significant, Intel remains the default choice for many large-scale deployments.

Why Intel Still Leads

OEM Relationships: Intel’s long-standing partnerships with PC makers guarantee design wins across desktops, laptops, and enterprise systems.
Product Portfolio: Intel offers a broader range of CPUs, covering entry-level, mainstream, and high-end segments more comprehensively than AMD.
Enterprise Trust: Intel’s reputation for reliability and support keeps it entrenched in data centers worldwide.
Mobile Strength: The laptop market, a massive volume segment, remains overwhelmingly powered by Intel.

AMD’s Historic Progress

AMD’s achievements should not be understated. Crossing 25 percent overall share and powering one-third of desktops marks its strongest position in decades. EPYC continues to chip away at Intel’s server dominance, and Ryzen has reshaped consumer perceptions of desktop performance. However, Intel’s entrenched advantages mean that AMD’s gains have not displaced Intel’s majority control.

Conclusion

As of late 2025, the x86 CPU market is more competitive than it has been in years. AMD has achieved historic progress, but Intel continues to dominate with a commanding majority across all major segments. The numbers are clear: AMD is stronger than ever, yet Intel still rules the x86 landscape.
