Summary of Global Server and AI Server Market Insights Industry Overview - The report focuses on the global server market, particularly AI training servers, AI inferencing servers, general servers, and high-performance computing (HPC) servers. It also discusses the capital expenditure (capex) trends of leading cloud service providers (CSPs) in the US and China. Key Insights Market Estimates and Growth Projections - The total addressable market (TAM) for global servers is projected to grow significantly, with estimates of US$433 billion, US$606 billion, and US$764 billion for the years 2025, 2026, and 2027 respectively, reflecting year-over-year growth rates of 71%, 40%, and 26% [18][27]. - AI server shipments are expected to increase to 2,605k units by 2027, with a notable rise in high-power AI servers, which are projected to grow by 56%, 67%, and 34% YoY from 2025 to 2027 [14][12]. AI Server Segment Insights - The report anticipates a total of 19k, 55k, and 80k full rack AI servers to be shipped in 2025, 2026, and 2027 respectively, with a TAM size of US$55 billion, US$165 billion, and US$255 billion for the same years [12][9]. - ASIC adoption in AI chips is expected to rise, accounting for 38%, 40%, and 50% of AI chips in 2025, 2026, and 2027 respectively, up from previous estimates [1][3]. Capital Expenditure Trends - Leading US CSPs are forecasted to increase their capex budgets by 78%, 37%, and 15% YoY from 2025 to 2027, an increase from previous estimates of 67%, 23%, and 15% [10][27]. - Chinese CSPs are also expected to grow their capex by 62%, 17%, and 9% YoY during the same period, up from 55%, 8%, and 6% [30][31]. AI Chip Demand - The demand for AI chips is projected to reach 11 million, 16 million, and 21 million units in 2025, 2026, and 2027 respectively, driven by the increasing volume of AI servers [1][9]. - The implied number of AI chips for training and inferencing is expected to be 20,838k units by 2027, with a mix of 50% GPU and 50% ASIC chips [22][23]. Additional Insights - The growth in AI server shipments is supported by the increasing applications of AI technologies and the introduction of new chip platforms, including AMD's "Helios" AI server rack [1][9]. - The report highlights the importance of baseboard-based AI servers, which offer greater customization and lower costs for clients, contributing to a more positive demand outlook [12]. Conclusion - The global server market, particularly in the AI segment, is poised for substantial growth driven by increased demand for AI infrastructure and significant capital investments from leading cloud service providers. The shift towards ASIC chips and diversified chip platforms is expected to further enhance market dynamics in the coming years.
