A graphics card, also known as a video card, GPU (Graphics Processing Unit), or graphics adapter, is a hardware component of a computer that is responsible for rendering images and videos on a display device, such as a monitor or TV.
Graphics cards works by receiving data from the computer’s CPU (Central Processing Unit) and transforming it into visual images that can be displayed on the monitor. The graphics card contains a dedicated processor, called the GPU, that is optimized for performing complex mathematical and graphical operations necessary for rendering images and videos.
The GPU consists of thousands of small processing units that work together to perform these operations in parallel, resulting in faster and smoother performance. The graphics card also has its own memory, called VRAM (Video Random Access Memory), which is used to store and access graphical data quickly.
Graphics cards are essential for gaming, video editing, 3D modeling, and other graphics-intensive applications that require high performance and visual quality. They come in different sizes, shapes, and capabilities, ranging from entry-level cards for basic tasks to high-end cards for professional use. Some graphics cards also support advanced features such as real-time ray tracing and AI-based upscaling to enhance visual quality and realism.
