# GPU versus CPU
- GPU stands for _Graphics Processing Unit_. Originally designed for rendering
graphics and video but now used for other applications of parallel computing
eg. machine learning.
- The standard CPU uses sequential processing whereas the GPU is designed for
parallel processing, specialising in performing many simple calculations
simultaneously.
- Harnessing the GPU requires specialised programming approaches.
- Most standard laptops and desktops (if they are not designed for
graphically-intensive tasks) incorporate graphics processing within the CPU.
The CPU chip is on the same chip as the CPU chip. This is called _integrated_
graphics processing.
- Some laptops, especially those marketed for gaming or professional work, have
a separate GPU chip. This is a more powerful graphics processor, separate from
the CPU.
