Multi-GPU refers to the use of multiple graphics processing units (GPUs) in a single computer system to enhance performance. This setup allows for parallel processing, where tasks are divided among the GPUs, leading to faster rendering and improved performance in graphics-intensive applications like video games and 3D modeling. In a Multi-GPU configuration, the GPUs can work together using technologies such as NVIDIA SLI or AMD CrossFire. This collaboration enables users to achieve higher frame rates and better visual quality, making it a popular choice for gamers and professionals who require powerful computing capabilities.
