AMD Loses Desktop CPU Share as Intel Regains Ground
AMD's share of desktop CPU shipments fell to 29.9% in Q3 2026, down from 34.9% in Q2, according to new Mercury Research data. Intel rose to 70.1%, and the figure marks AMD's lowest desktop share since early 2025.
Mercury says it isn't certain what drove the swing. Its best estimate points to weaker laptop demand, which may have encouraged Intel to shift more chips into desktops during the seasonal third-quarter increase. Intel had been under-supplying that market earlier in the year, and AMD does not appear to have captured the same seasonal lift.
Mercury also highlights AMD's heavier exposure to PC gaming, a segment it says has been affected by supply constraints on gaming GPUs. AMD has acknowledged that demand is running ahead of what it can ship, and Lisa Su has described the company as 'data center first.'
For anyone watching the PC hardware business, the lesson is that supply, channel mix and segment exposure can move market share quickly. Those are worth tracking closely.

- The key numbers Intel rose to 70.1%. AMD's 29.9% is its lowest desktop figure since early 2025, when it sat at around 28%.
- Why it matters Mercury isn't sure of the cause. It suggests weaker laptop demand and AMD's heavier PC gaming exposure may be factors.
