Grafiikkakiihdyttimillä

Grafiikkakiihdyttimillä, often referred to as GPUs (Graphics Processing Units), are specialized electronic circuits designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. While their primary purpose is to render graphics for video games and visual applications, their parallel processing capabilities have led to their use in a wide range of other tasks.

The architecture of a GPU differs significantly from that of a central processing unit (CPU). GPUs contain thousands of smaller, more efficient cores designed to handle multiple tasks simultaneously, making them ideal for parallel processing. This contrasts with CPUs, which have a few powerful cores optimized for sequential tasks. This parallel processing power is crucial for tasks like rendering complex 3D scenes, video editing, and scientific simulations.

Initially, GPUs were integrated into graphics cards, but modern GPUs are also found integrated into CPUs (integrated graphics) or as standalone chips in mobile devices and consoles. The development of GPUs has been a driving force behind advancements in visual computing and has enabled increasingly sophisticated and realistic graphics in consumer electronics and professional applications. Their ability to perform massive parallel computations has also made them indispensable tools in fields such as artificial intelligence, machine learning, and cryptocurrency mining, where complex calculations need to be performed rapidly.
