What Is Graphics Processing Unit (GPU)? by Thephantomweb: 10:01am On May 14, 2017
A Graphics processing unit (GPU), is a specialized electronic circuit just like a Central processing unit(CPU) design to rapidly manipulate and send graphical information to a display device. such as a computer monitor, TV, or projector. The GPU performs rapid mathematical calculations primarily to renders images, animations and video for the computer’s screen.

A graphics processing unit is able to render images more quickly than a central processing unit(CPU) because of its parallel processing architecture, which allows it to perform multiple calculations at the same time. GPU are essential for smooth decoding and rendering of 3D animations and video and also use in 2D such as for zooming and panning the screen. The more processing power of the GPU, the higher the resolution and the faster and smoother the motion in games and movies. GPUs can be found in mobile phones, personal computers, workstations, and game consoles.

Nvidia and AMD are the two major manufacturers or GPU, but Intel usually build an Integrated graphics card to most CPU.

Note: A video card or Graphics card is an expansion card which actually the overall hardware of the GPU.

Types of Graphics processing unit (GPU)
In personal computers(PC), there are two main forms or types of GPUs.

Integrated graphics card

A Integrated graphics card also know as integrated graphics processors (IGP) is a shared resource type of graphics card. It utilize a portion of the computer’s system RAM to perform the graphics processing needed. Example of Integrated graphics card is Intel HD graphics and AMD APU. Generally Integrated graphics have low processing power thus very cheap. There are not a ideal for 3D gaming or rendering high resolution video like 4k.

Dedicated graphics card

Today will bring to discuss on Graphics processing unit (GPU), I know you have been hearing the term GPU, Graphics card or video card.
A dedicated graphics card, also know as discrete GPU, has own independent source of video memory,i.e RAM. Which is connected to the motherboard though extension slot such as PCI Express (PCIe). Example a Nvidia GeForce GTX 680M video card with 2GB of video memory. dedicated graphics card are perfect if you are into serious gaming, high resolution video playback or rendering or professional graphic design.

There are also other types of Graphics processing unit (GPU) such as Hybrid graphics processing and External GPU (eGPU).
