High-bandwidth memory technologies significantly increase data transfer rates between GPU cores and memory modules.
Large transformer models perform extensive matrix multiplications during inference. While compute throughput is critical, memory bandwidth frequently becomes the limiting factor. GPUs must rapidly move parameter data between memory and processing cores. In 2023 performance analyses emphasized bandwidth bottlenecks for LLaMA-scale deployments. Insufficient bandwidth increases latency even if compute units remain underutilized. Hardware vendors optimized memory architectures to address this constraint. Developers profiled inference workloads to identify transfer inefficiencies. Performance tuning required balancing arithmetic intensity and memory flow. Intelligence traveled at memory speed.
