Graphics cards are specialized electronic components designed to render visual content onto computer displays, be it for desktops, laptops, or even in-car systems. They serve as the engine that processes and translates data into images, ensuring smooth and high-quality visuals. By offloading this task from the central processing unit (CPU), graphics cards enable more efficient overall system performance. They come equipped with their own memory known as Video Random Access Memory (VRAM) and boast impressive specifications such as core clock speed, memory bandwidth, and CUDA cores or Stream Processors for parallel processing tasks. High-end models cater to demanding applications like gaming, 3D modeling, and video editing, offering advanced features such as real-time ray tracing, hardware encoding/decoding, and multiple display outputs.
