General-purpose computing on graphics processing units

General-purpose computing on graphics processing units (GPGPU) is the use of special processors called graphics processing units (GPUs) to do tasks that were traditionally done with a central processing unit (CPU). GPUs are processors that have been designed to quickly draw 3D graphics. GPGPU is the use of these processors to do tasks that aren't related to graphics, like working with large spreadsheets, analyzing data, solving complex problems, and more. GPUs are made to be very efficient and fast, and they can do these types of tasks much quicker than a CPU can. GPGPU is a way of getting more out of the processor and it can help computers work more quickly and efficiently.
