AMD introduced the Helion rack, a reference design for agentic AI data centers, offering up to 32,768 CPU cores. It comes in two configurations: CPU-only for hyperscale data centers and an integrated CPU-GPU rack for enterprises. AMD aims to compete with Nvidia in AI infrastructure, with partners like Cisco and Dell on board. AMD's revenue grew 50% to $11.5 billion last quarter, and its stock has risen 182% in the past year.

AMD acquired World Labs, led by Dr. Fei-Fei Li, for approximately $8.2 billion in an all-stock deal. The acquisition aims to enhance AMD's AI hardware and software development capabilities, particularly in spatial-intelligence models for 3D environments. AMD's CEO and Dr. Li highlighted the potential for accelerated AI research and infrastructure development, though integration challenges and stock performance fluctuations are noted.

AMD (NASDAQ:AMD) reports strong demand for its server CPUs, exceeding forecasts. CEO Lisa Su notes supply constraints but expects substantial supply increases by 2027.
