Semiconductor foundry GlobalFoundries recently indicated that the server CPU market is entering a structural growth "super cycle," driven by surging demand for AI inference and agent applications, with Advanced Micro Devices, Intel, and Qualcomm positioned as major beneficiaries.
During the earlier AI training phase, which was dominated by GPUs, the ratio of GPU to CPU usage was approximately 8:1. As AI applications rapidly shift toward inference and agents, this ratio has dropped to 4:1 and may even approach 1:1 in the future. The importance of CPUs in data orchestration, memory management, and system coordination has significantly increased. GlobalFoundries now views AI server CPUs as a key growth driver and has committed to returning 50% of its free cash flow to shareholders.
Regarding the competitive landscape, Advanced Micro Devices reported data center revenue of approximately $5.8 billion in the first quarter of 2026, surpassing Intel's $5.1 billion for the first time, with its server market share nearing 50%. AMD management has raised its total addressable market forecast for server CPUs in 2030 from $60 billion to $120 billion. For Intel, despite facing capacity constraints, server CPU demand has rebounded strongly. The company has increased its capital expenditure for 2026 to expand production and has secured Tesla as a key partner for its 18A process technology. Additionally, Qualcomm is developing data center-class CPUs based on Arm architecture, which could debut as early as June 2026, introducing a third competitive force into the market.
The current supply bottleneck lies in HBM and advanced packaging capacity rather than wafer capacity, giving an advantage to companies with established packaging partnerships. Analysts believe this demand growth is structural rather than a short-term fluctuation, indicating that server CPUs have re-entered a long-term growth trajectory.
