GPU Architecture refers to the design and structure of a Graphics Processing Unit, which is specialized hardware for rendering images and processing complex calculations. Unlike a CPU, which is optimized for sequential tasks, a GPU consists of many smaller cores that can handle multiple operations simultaneously, making it ideal for parallel processing tasks such as graphics rendering and machine learning. The architecture of a GPU typically includes components like memory, processing cores, and a memory controller. These elements work together to efficiently manage data and execute tasks. Modern GPUs also support advanced features like ray tracing and tensor cores to enhance performance in graphics and artificial intelligence applications.
