Yes, GPUs can also be utilized for non-graphics-related computing tasks, such as scientific calculations and machine learning. This is known as GPGPU (General Purpose Computing on Graphics Processing Units) computing.
However, not all GPUs are suitable for GPGPU computing, and it is important to check the capabilities of a specific GPU before utilizing it for these tasks.
Additionally, CPUs may still be more efficient for some non-graphics-related tasks. So it is important to consider both the capabilities of the GPU and the specific requirements of the task before using a GPU for non-graphics related computing.
