The RIVA 128, or "NV3", was a consumer graphics processing unit created in 1997 by Nvidia. It was the first to integrate 3D acceleration in addition to traditional 2D and video acceleration. Its name is an acronym for Real-time Interactive Video and Animation accelerator.

A graphics processing unit (GPU) is a specialized electronic circuit initially designed to accelerate computer graphics and image processing. After their initial design, GPUs were found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure. Other non-graphical uses include the training of neural networks and cryptocurrency mining.
