What is graphics accelerator?
A graphics accelerator is dedicated hardware that is designed and used to process visual data quickly. It's a full computer in itself as it has its own processor, RAM, buses, and even I / O mechanisms that it uses to interface with the computer system; In modern computers, this is the PCI-E port.
Graphics Accelerator is an older term for the graphics processing unit (GPU).
The graphics accelerator is used to increase the performance of a computer system by offloading various data processing tasks from the CPU. These tasks are often visual in nature and / or have something to do with graphics that frees the processor to do other tasks.
The graphics accelerator is a special type of processor that is similar to an application specific integrated circuit (ASIC) in that it is only intended to process graphics data and not much more. When there is less graphical processing required in an application, the graphics accelerator doesn't do much other than output the GUI to the screen.
They are known as graphics accelerators because they are especially useful for graphics-intensive tasks such as:
- Rendering of 3D models and images
- video editing
Graphics accelerators are used in industries such as:
- Computer aided design (CAD)
- Films for special effects
- video games
Graphics accelerators are now not only present in PCs and laptops, but also in many mobile devices such as tablets and smartphones.
