GPUs & Their Uses

A graphical processing unit (GPU) is now an essential feature in a gaming PC. They help display the output from your computer, but can be used for a whole lot more.

GPUs

GPUs

  • GPU stands for graphical processing unit.
  • A GPU is designed and made for processing graphical output from your computer system.

CPUs vs GPUs

CPUs vs GPUs

  • A CPU processes tasks in a serial order (one after another).
  • A GPU has lots of smaller cores that are very efficient at processing large amounts of visual data in smaller chunks simultaneously (in parallel).
Uses of GPUs

Uses of GPUs

  • A GPU is usually used to process the graphical information for a computer to output what the user is doing.
  • A GPU is also very useful for mining blockchain cryptocurrencies such as Bitcoin.
  • They are also often used in supercomputers as a parallel processor where a lot of data needs to be processed simultaneously.
  • These supercomputers could be for scientific use and engineering use.
