Multi-GPU technology 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 frame rates in applications like gaming and 3D modeling. This technology can be implemented through various methods, such as NVIDIA's SLI or AMD's CrossFire, which enable the GPUs to work together efficiently. Multi-GPU configurations are particularly beneficial for demanding tasks, including machine learning and video editing, where increased computational power is essential.
