AI servers demand massive memory: 20TB HBM and 17TB RAM per unit

A single 72-GPU GB300 NVL72 AI server requires over 20 terabytes of high-bandwidth memory, primarily for GPUs and other AI chips. Additionally, these servers utilize 17 terabytes of LPDDR5X RAM, similar to that found in mobile devices. A gigawatt data center could house thousands of these NVL72 servers, highlighting the immense memory demands of AI. AI
