High-bandwidth memory (HBM) addresses that problem by placing stacked memory close to the compute package, increasing the amount of data that can move between memory and processor. It has become one of the defining components of modern AI infrastructure—and a constraint that is easy to miss when attention is focused on GPUs.",[16,17,19],"h2",{"id":18},"bandwidth-is-a-system-property","Bandwidth is a system property",[12,21,22],{},"An accelerator cannot use theoretical compute performance if memory cannot feed it. The useful result depends on the model, batch size, precision, interconnect, software kernels, and thermal envelope. Adding more HBM can improve capacity and bandwidth, but it also adds cost, power, and packaging complexity.",[12,24,25],{},"This makes memory planning part of product design from the beginning. A chip team, a memory supplier, and a packaging partner must coordinate roadmaps months or years before a product reaches a data center.
