Grafiikkokorttien, or graphics cards, are essential hardware components in modern computers responsible for processing and rendering images, videos, and animations for display on a monitor. Also known as video cards or GPUs (Graphics Processing Units), they are specialized processors designed to handle the complex calculations required for visual output.

The primary function of a graphics card is to accelerate the rendering of 3D graphics, which is crucial for video games, professional design software, and even everyday desktop tasks. Modern graphics cards contain dedicated memory, known as VRAM (Video Random Access Memory), which stores texture data, frame buffers, and other graphical assets, allowing for faster access and processing.

Graphics cards come in various forms, from integrated graphics built directly into a computer's CPU or motherboard to discrete, standalone cards that offer significantly more power and performance. Discrete graphics cards are favored by gamers, video editors, and graphic designers who require high-fidelity visuals and demanding processing capabilities.

The performance of a graphics card is determined by several factors, including its core clock speed, the number of processing cores, the type and amount of VRAM, and its memory bandwidth. Advancements in graphics card technology have led to features like real-time ray tracing and AI-powered upscaling, further enhancing visual realism and gaming performance.
