They certainly can, but since they need to compute the individual components serially, there’s a vast difference in their performance compared to a GPU. This is not to say that CPUs can’t process these components. This is why you need to use a graphics processing unit (GPU) along with a CPU to properly render graphics. Most graphical tasks require more powerful parallel processors with multiple cores as each individual render requires numerous components to be processed at the same time. It is a serial processor that handles all the non-graphics processing.
