A graafikaprotsessori, commonly known as a graphics processing unit (GPU), is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. Unlike the central processing unit (CPU), which executes general-purpose instructions, GPUs are optimized for parallel processing tasks, making them highly efficient for tasks involving graphics rendering, video editing, and computational workloads.

GPUs were originally developed for rendering two-dimensional graphics in personal computers and workstations. Over time, their capabilities expanded significantly, enabling real-time rendering of three-dimensional graphics, which is essential for modern video games, simulations, and visual effects in film and television. Today, GPUs are also widely used in fields such as artificial intelligence, machine learning, scientific computing, and cryptocurrency mining due to their ability to handle large-scale parallel computations.

The architecture of a GPU typically includes thousands of smaller, more efficient cores compared to a CPU, allowing it to process multiple tasks simultaneously. This parallel processing capability makes GPUs particularly well-suited for tasks that can be broken down into smaller, independent operations, such as shading, texturing, and lighting calculations in 3D graphics. Additionally, GPUs often feature dedicated memory (VRAM) to store and manipulate graphical data quickly.

Modern GPUs are produced by several major manufacturers, including NVIDIA, AMD, and Intel, each offering a range of products tailored to different markets, from consumer gaming to professional workstations and high-performance computing. The performance of a GPU is often measured by benchmarks that evaluate its rendering speed, power efficiency, and support for advanced features such as ray tracing and AI acceleration. As technology continues to advance, GPUs are expected to play an increasingly important role in both entertainment and computational applications.
