This roadmap offers an introduction to GPU architecture for those new to the technology, emphasizing the differences between GPUs and CPUs. It outlines objectives such as understanding GPU features, implications for program construction in GPGPU, and specifics about NVIDIA GPU components. Familiarity with high-performance computing concepts may be beneficial but is not required.

The article discusses the evolution of GPU architecture, emphasizing the growing disparity between the increasing performance of GPUs and the limited data bandwidth available through traditional buses like PCI Express. It argues for a reevaluation of how data is moved to and from powerful GPUs, highlighting the need for new architectures to address bottlenecks in performance and energy efficiency.
