AMD closed 2025 with record-breaking market share gains across every computing segment, according to Mercury Research’s Q4 2025 report. The chipmaker achieved 41.3% server revenue share driven by EPYC adoption, while desktop revenue share surged to 42.6% on Ryzen demand.

These gains underscore AMD’s execution and customer confidence in its data center and client computing leadership.

Segment	Revenue Share	Q/Q Growth	Y/Y Growth
Server	41.3%	+1.8 points	+4.9 points
Desktop	42.6%	+1.6 points	+14.6 points
Mobile	24.9%	+3.3 points	+3.3 points
Total Client	31.2%	+3.0 points	+7.4 points
Overall CPU	35.4%	+2.9 points	+6.8 points

Server Dominance: EPYC Reaches Historic High

AMD’s server business hit 41.3% revenue share in Q4 2025, up 4.9 points year-over-year. Unit share reached 28.8%, reflecting accelerated EPYC adoption across cloud and enterprise data centers.

This represents AMD’s highest server share ever—a dramatic shift from sub-5% share before EPYC’s introduction. Cloud hyperscalers choose EPYC for superior performance-per-watt, core density, and TCO advantages over Intel Xeon.

Desktop Surge: Ryzen Captures 42.6%

AMD’s desktop business delivered 42.6% revenue share—up 14.6 points year-over-year. Desktop unit share reached 36.4%, showing strong Ryzen demand.

The 14.6-point annual gain represents one of AMD’s largest desktop increases, driven by Ryzen 7000/9000 series gaming leadership, AM5 platform longevity, competitive pricing, and enthusiast preference.

AMD now controls over 42% of desktop revenue—nearly matching Intel in this traditionally Intel-dominated segment.

Mobile Progress and Overall Gains

Mobile reached 24.9% revenue share (up 3.3 points Y/Y), showing steady notebook processor adoption. Total client share hit 31.2%, while overall CPU revenue share reached 35.4%—meaning AMD controls over one-third of total x86 processor revenue.

What’s Driving AMD’s Momentum?

Server: EPYC Genoa/Bergamo with Zen 4, AI/ML optimization, energy efficiency, cloud partnerships (AWS, Azure, Google)

Desktop: Ryzen 7000/9000 gaming performance, AM5 platform, competitive pricing, enthusiast market dominance

Mobile: Ryzen 7040/8040 series, OEM design wins (HP, Dell, Lenovo), premium laptop penetration

Intel’s Challenge

AMD’s gains come at Intel’s expense as Intel faces manufacturing delays, EPYC competition in servers, Core i9 instability issues, and increased Qualcomm/Apple mobile competition.

Market Implications

AMD’s Q4 2025 results validate multi-generational Zen architecture investments and high-margin server focus. For customers, share growth means competitive pricing, innovation pressure, ecosystem investment, and supply diversification.
