Over 4,500 chips in AI server racks… accounting for over 95% of component value

A single advanced AI server rack contains more than 4,500 packaged semiconductor chips, which account for over 95% of the rack's component value, according to a "Powering AI" report released June 1 by the U.S. Semiconductor Industry Association (SIA) and Deloitte. The figure refers to component value for the rack examined, not total data center construction costs. The rack's chips span AI accelerators, CPUs, high-bandwidth memory (HBM), DRAM, NAND flash, and networking and power-management silicon, underscoring how semiconductor content dominates AI infrastructure spending across compute, storage, data movement and power delivery. The finding matters because it quantifies how much of AI server value flows to chip suppliers rather than assembly or other components. Next, watch whether the 95% share holds across other rack configurations and how HBM and accelerator content shifts as next-generation AI systems scale.
