AMD and Arm Continue to Gain CPU Market Share From Intel in Q3, BofA Says

Advanced Micro Devices (AMD, Financials) and Arm extended their share gains over Intel in the third quarter, according to Bank of America, which pointed to new Mercury Research data showing stronger unit growth across both PCs and servers.

Analyst Vivek Arya said Intel's performance remained constrained by supply limitations at its 7-nanometer and 10-nanometer processes, which kept overall output in check. Intel's Q3 unit growth was modest at 2% in PCs and a 1% decline in servers. By comparison, AMD recorded 10% growth in PCs and 1% in servers, while Arm posted 7% and 16% growth, respectively.

Intel's average selling prices rose in the quarter, but AMD continued to show stronger pricing trends, supported by a 35% year-over-year increase in PC chip ASPs and a 3% gain in server chips. Arya said Intel's shortages likely boosted AMD's notebook shipments and helped sustain its desktop outperformance.

Arm's position in servers continued to strengthen, with higher core counts driving more than 100 basis points of quarterly unit and value share, according to the report. BofA said AMD and Arm remain well-positioned due to broader opportunities in servers and PCs, while Intel faces ongoing challenges across both its x86 portfolio and foundry roadmap.

Looking ahead, the bank described PC market expectations for 202526 as conservative but said AMD and Arm should keep benefiting from server demand tied to AI. AMD recently estimated that the server CPU market could exceed $60 billion by 2030, though BofA's forecasts for 202728 remain closer to $33 billion to $36 billion.
