Surge in Data Center Semiconductor Demand Driven by AI Hardware Expansion in 2Q 2025

Data Center Semiconductor Demand Surged by AI Growth in 2Q 2025

According to a recent study from the Dell'Oro Group, a leading source for telecommunications and market information, the second quarter of 2025 experienced a remarkable 44% year-over-year growth in the sales of semiconductors and components used in data centers. This substantial increase can be largely attributed to the surging demand for AI hardware, which has reshaped the landscape of server and storage markets.

Key Insights from the Report

The report emphasizes that the robust demand for various components, particularly accelerators, High Bandwidth Memory (HBM), and Network Interface Cards (NICs), underpins the expanding AI infrastructure stack. As Baron Fung, the Senior Research Director at Dell'Oro Group, noted, the impact of this growth was particularly pronounced for GPUs designed for AI workloads, which have led the charge in market expansion.

Specifically, the quarter saw substantial contributions from NVIDIA's Blackwell Ultra GPUs, as well as custom accelerators produced by tech giants Google and Amazon. The increased adoption of these state-of-the-art technologies has positioned them in direct competition with traditional commercial GPUs, albeit with varied applications across AI and cloud solutions.

Additionally, the report outlines a mixed picture for the overall market, mentioning factors such as tariffs and inventory adjustments, which may have influenced revenue trends. Despite these short-term dynamics, the demand for general-purpose server components such as CPUs and NICs shows a positive long-term trajectory.

Market Forecast

Looking ahead, the Dell'Oro Group forecasts a further 46% growth in the server and storage system component market throughout 2025. This continued upswing reinforces the significance of key players in the industry, with NVIDIA leading in revenue generated from data center IT components. Following NVIDIA, other notable companies like SK Hynix and Samsung have also seen revenues climb thanks to increasing HBM demand and trends in the general server market.

ARM CPUs are becoming increasingly prominent, now holding a solid 25% of the server market share, in part due to advancements made by NVIDIA's GB200 and GB300 chips along with custom deployments driven by hyperscale operators. Their presence reflects a growing trend towards ARM architectures in high-performance computing environments.

The report also highlights the doubling of revenue from Smart NICs and Data Processing Units (DPUs) over the past year, driven by an upsurge in the deployment of Ethernet adapters specifically designed for AI clusters. This emphasizes the industry's shift towards specialized hardware tailored for optimal performance in AI-centric applications.

Conclusion

The data center semiconductor market in 2Q 2025, driven by the insatiable appetite for AI hardware, stands as a testament to the ongoing technological evolution that is reshaping data processing.
