grafiikkapiirejä

Grafiikkapiiri, or 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. GPUs are highly parallel, meaning they can perform many calculations simultaneously. This parallel processing capability makes them ideal for tasks that involve rendering complex graphics, such as in video games, computer-aided design (CAD) software, and scientific simulations.

Initially, graphics were handled by the central processing unit (CPU) of a computer. However, as graphics became more sophisticated, the need for dedicated hardware arose. The first GPUs emerged in the 1990s, offering significant improvements in rendering speed and visual quality. Modern GPUs are incredibly powerful, capable of rendering photorealistic images and processing vast amounts of visual data in real-time.

Beyond gaming and professional visualization, GPUs have found applications in other fields. Their parallel processing power makes them well-suited for machine learning and artificial intelligence tasks, including training deep neural networks. They are also used in cryptocurrency mining and scientific research, such as in physics simulations and molecular modeling. The development of GPUs continues to push the boundaries of visual computing and computational power.
