UBS: AMD, ARM Deepen Q1 Server CPU Share Gains at Intel's Expense

A May 14 UBS report details AMD and ARM accelerating server CPU share gains from Intel in Q1 2026, with total shipments up 6% q/q (19% y/y) driven by hyperscaler capex and agentic AI. Intel's unit share fell to 54.9% (-370 bps), AMD rose to 27.4% (+230 bps), and ARM to 17.7% (+140 bps); in x86 servers, AMD shipments jumped 15% q/q vs Intel's 1% decline, yielding revenue shares of 46.2% vs 53.8%. This builds on initial May 13 findings amid weak PC shipments (down 13% q/q), with UBS projecting server CPU market expansion to $170bn by 2030 and ARM at 40-45% units.
