Intel’s desktop x86 CPU shipment share jumped to 70.1% in Q3 2026 from 65.1% in Q2, according to Mercury Research figures reported by HotHardware. AMD’s share fell from 34.9% to 29.9%. Source Source
That’s a swing of about five percentage points. Wccftech notes that these figures measure processor shipments, not end-user purchases. They don’t establish that gamers abandoned Ryzen. Source
Weaker laptop demand may have helped Intel
“It's difficult to know the driver of this for sure,” Mercury Research president Dean McCarron wrote in an email quoted by HotHardware. He speculated that weaker demand for mobile CPUs may have let Intel allocate more products to desktops, where demand normally rises in the third quarter. Intel had been under-supplying that market earlier in 2026, he added. Source
According to TechPowerUp’s account, Mercury points to supply constraints on gaming graphics cards as a drag on the gaming-PC market, where AMD has greater exposure. That could help explain why AMD apparently missed the usual seasonal lift. A desirable CPU still can’t finish the rest of a gaming PC’s parts list by itself. Source
AMD gained in servers, not the lead
The server results went the other way. From Q2 to Q3, AMD’s server CPU shipment share, excluding Internet of Things products, rose from 34.5% to 35.5%. Intel retained a clear lead at 64.5%, down from 65.5%, according to the reported Mercury figures. Source Source
Across the overall x86 market, HotHardware reports that Intel’s share edged up from 65.9% in Q2 to 66.1% in Q3, while AMD’s slipped from 34.1% to 33.9%. Source
