Because the faster those units know where they are going to move or what they are going to shoot, the faster the graphics card can render their actions.
If you have 20 enemies running around, and they are all independent of each other's actions, they will all need to process where they are going and what they are going to do to you. If you can use 4 threads for those calculations then the graphic interface for those actions can then be processed. You can't render something that hasn't be executed by the AI.
Also for lighting effects, the cpu has to decide where the units are going to move and this will effect hose these lighting effects are going to be changed and from what angles in all kinda of more realistic ways.
