Nvidia's next-generation Blackwell processors are facing significant challenges with overheating when installed in high-capacity server racks, reports The Information. These issues have reportedly led to design changes and delays and raised concerns among customers like Google, Meta, and Microsoft about whether they can deploy Blackwell servers on time.
According to insiders familiar with the situation who spoke with The Information, Nvidia's Blackwell GPUs for AI and HPC overheat when used in servers with 72 processors inside. These machines are expected to consume up to 120kW per rack. These problems have caused Nvidia to reevaluate the design of its server racks multiple times, as overheating limits GPU performance and risks damaging components. Customers reportedly worry that these setbacks may hinder their timeline for deploying new processors in their data centers.
