AMD hits an all-time high x86 CPU market share record, now holding a third of the server market

AMD has hit an all-time high in overall x86 CPU market share, reaching 32.6% in Q1 2026, according to Mercury Research. A year ago, that number was 27.1%, meaning AMD has gained nearly 6 percentage points in a single year. Intel still leads with 67.4%, but that figure is down from 72.9% a year ago and down sequentially from 68.6% last quarter.

The server market is where AMD's momentum is most visible. The company now holds 33.2% of x86 server CPU shipments, up from 27.2% a year ago and 30% last quarter, meaning AMD now controls roughly a third of a market Intel has long dominated. Overall server CPU unit shipments were more than 10% higher year-on-year, driven almost entirely by AI data center demand. Intel's server shipments remained relatively flat both sequentially and year-on-year. A separate Mercury Research report previously showed that AMD's EPYC CPUs accounted for 46.2% of total server CPU spending in Q1 2026.

AMD's unit shipments increased by nearly 17% year over year, while Intel's declined by more than 10%, a gap that explains the five-and-a-half-point swing in overall share over the same period. Last year, Intel decided to allocate more production capacity to server chips, which had a knock-on effect on other product lines, and AMD benefited. Across the entire x86 processor market, AMD also secured close to a third of all shipments. Worth noting is that this figure includes console SoCs, where AMD has a near-monopoly. Stripping those out, AMD's share of the broader CPU market stood at 30%, still up from 29.3% in the previous quarter and 24.4% year on year.

The firm says the total volume of x86 processor chips shipped was lower during this quarter than the previous one, which is seasonally typical, but the drop this year was steeper than usual. A bright spot for Intel was the desktop CPU market. The overall desktop market had a difficult quarter, and AMD surprisingly underperformed Intel in this segment. This allowed Team Blue to recover some ground and push its desktop share back up to 66.8% from 63.6% last quarter. In mobile, the decline was more modest and ran entirely in AMD's favor. Intel's supply constraints on laptop CPUs pushed its mobile share down, while AMD's share rose to 28.3% from 22.5% a year ago.

Looking outside the x86 sphere, ARM is also gaining ground, with ARM server chip shipments nearly doubling compared to a year ago. Mercury Research notes that its ARM estimates carry some uncertainty, but the boom around Apple's MacBook Neo and NVIDIA's entry into the PC platform space with RTX Spark will only push those numbers further. That said, both Intel and AMD have indicated that the server CPU outlook for the rest of 2026 is strong, with Intel recently launching Xeon 6+ Clearwater Forest server CPUs.
