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.
