What Does Desktop Supercomputer Mean?
A desktop supercomputer is a desktop computer that has performance like that of a supercomputer. A desktop supercomputer typically possesses a fast GPU, often with several of them for boosting performance as well as multiple CPU cores. Desktop supercomputers are designed for scientific and technical computing, such as physics simulations and medical imaging.
Techopedia Explains Desktop Supercomputer
Desktop supercomputers are desktop computers designed for technical computing. This can include computing physics problems or building 3-D images. One design goal for these computers is to offer performance that is as close to a supercomputer as possible. System builders achieve this by using GPUs to perform computations. Desktop supercomputers usually use workstation-class graphics processors. GPUs can perform calculations quickly because they can execute many calculations in parallel.
