ARM Vs. AMD: Who Is Going to Win the Agentic AI CPU Revival War?

In the rapidly evolving agentic AI CPU market, two industry giants, AMD and ARM, released earnings reports that highlighted their respective strategies and positions. AMD reported a record Q2 FY2026 revenue of $11.54 billion, up 50.1% year-over-year, driven by its EPYC and Instinct products. Lisa Su, AMD's CEO, shared that the Data Center segment grew to $6.7 billion, or 58% of total revenue, up from 42% a year prior, with cloud and enterprise divisions each expanding more than 70%.

The upcoming 6th Gen EPYC Venice, utilizing Zen 6 and 2nm technology, is designed to deliver superior performance per watt compared to ARM-based CPUs. On the other hand, ARM disclosed a 22.4% year-over-year revenue growth to $1.29 billion in Q1 FY2027. However, ARM's story now centers around its newly developed production chip targeting the same workloads as AMD's offering.

ARM's CEO, Rene Haas, stated that demand for the AGI CPU exceeds $2 billion as new customers, including US and Chinese entities, continue to sign up. Despite ARM's operating margin compressing to 7% from 11%, and missing EPS estimates by 38.09%, the company's AGI CPU shipments have surpassed 1.5 billion cores, with 500 million shipped in just nine months.

ARM's share in CPU compute among top hyperscalers is estimated at around 50%, which could potentially increase if it decides to produce its own silicon, like AMD. Both companies face unique challenges in this competitive landscape, with AMD demonstrating stronger fundamentals and revenue growth, while ARM's speculative bet is contingent on the successful launch of its AGI CPU and its ability to maintain margins in a highly competitive market.
