AMD’s CPU business closed 2025 on an unprecedented high, with its Ryzen and EPYC lines capturing their largest-ever market share in both units and revenue. The numbers, compiled by industry analyst firm Mercury Research, reveal a company that has not only stabilized its growth but accelerated it—especially in the desktop segment, where Ryzen CPUs now command nearly half of all sales by revenue.
The most striking figure is desktop revenue share, which jumped 14.6 percentage points year-over-year to 42.6%, the highest since Ryzen’s 2017 launch. Unit share also rose to 36.4%, up from 26.9% in the same quarter of 2024. This surge isn’t just about new chips like the Ryzen 7 7800X3D or 9800X3D; older AM4-based processors, including the Ryzen 7 5800X, are still outselling many competitors, fueled in part by high RAM prices making upgrades less appealing.
Key specs behind the desktop push
- AM4 platform longevity: CPUs like the Ryzen 7 5800X (8 cores/16 threads, 3.8 GHz base/4.7 GHz boost) remain competitive on AM4 motherboards, benefiting from LPDDR6 support in some configurations.
- 3D V-Cache dominance: The Ryzen 7 7800X3D (8 cores/16 threads, 4.2 GHz base/5.0 GHz boost) leads in gaming performance with its stacked cache, while the Ryzen 9 9800X3D (8 cores/16 threads, 4.2 GHz base/5.1 GHz boost) targets enthusiasts.
- Price-to-performance: Even mid-range Ryzen 5 and Ryzen 3 models are holding their own against Intel’s offerings, particularly in budget builds.
This desktop dominance isn’t isolated. AMD’s mobile CPU unit share grew to 26.0% (up 4.1 points year-over-year), while revenue share reached 24.9%, driven by Ryzen AI MAX series chips and the upcoming Ryzen AI 400 lineup. These chips, which integrate AI accelerators and support LPDDR6 memory, are positioning AMD to compete directly with Intel’s latest Core Ultra series.
On the server side, AMD’s EPYC CPUs also set records. Revenue share hit 41.3%, up 4.9 points year-over-year, as Genoa and Turin-based servers remain in high demand. The upcoming Venice architecture (Zen 6) is expected to further solidify this lead, though its launch is targeted for mid-2026.
What’s holding AMD back?
The most notable constraint is the DRAM shortage, which has slowed some high-end product releases. Additionally, while Ryzen’s 3D V-Cache chips excel in gaming, their power draw and heat output can be a drawback in compact or air-cooled builds. Intel still holds a slight edge in raw single-threaded performance for some workloads, though AMD’s multi-threaded strength in productivity tasks remains unmatched.
Looking ahead, AMD’s trajectory depends on two key factors: the rollout of Zen 6-based CPUs and its ability to maintain momentum in the AI PC market. With the Ryzen AI MAX series and LPDDR6 support, AMD is betting heavily on AI workloads, but whether this translates to sustained consumer adoption remains to be seen.
The bottom line? AMD’s Q4 2025 results confirm it’s no longer just a challenger—it’s the leader in CPU revenue share, with Ryzen and EPYC setting benchmarks across desktop, mobile, and server segments. The question now is whether this momentum can carry into 2026 as Intel responds and new architectures take center stage.
