# CPU vs GPU

-   CPU -- **Central Processing Unit**

    -   A CPU can never be fully replaced by a GPU

    -   Can be thought of as the **taskmaster** of the entire system, coordinating a wide range of general-purpose computing tasks

-   GPU -- **Graphics Processing Unit**

    -   GPUs were originally designed to create images for computer graphics and video game consoles

    -   GPGPU

    -   Performing a narrower range of more specialized tasks

- GPU is like the turbo boost to a car's engine, the CPU. 

  -   A computer can't function without a CPU. 
  -   Not all computers have GPUs.
