GPUs

Definition

GPUs, or Graphics Processing Units, are specialized hardware designed to accelerate the rendering of images and video by processing multiple tasks simultaneously. Unlike CPUs, which are optimized for sequential task execution, GPUs excel in parallel processing, making them essential in high-performance computing applications such as machine learning, gaming, and image processing. This parallel architecture allows GPUs to perform complex calculations more efficiently, significantly impacting hybrid optical-electronic computing systems.
