A single CPU does not have this capability, although multicore processors can perform calculations in parallel by combining more than one CPU onto the same chip.
A CPU also has a higher clock speed, meaning it can perform an individual calculation faster than a GPU.
Therefore, a CPU is often better equipped to handle basic computing tasks.
Specialized chips for processing graphics have existed since the dawn of video games in the 1970s.
While newer games get the bulk of the attention, even some older games see a significant increase in performance with updated drivers.
