A Gamers Guide to Graphic Cards

Graphics Cards

Whether You’re watching your favorite movies on the computer, playing massively multiplayer online games or just simply scanning or downloading images over the Web; the quality and degree of the graphics you encounter is just as good as the video card you’ve installed.

A Intel Integrated Graphics Card identifies any computer device or program which makes a computer capable of displaying and manipulating images. It’s a computer component designed to convert the logical representation of visual data into a signal which may be applied as input for a display medium.


Most of These graphics cards have additional functions including the following: rapid rendering of 3D scenes and 2D images; movie recording; as TV-tuner adapter; decoding of MPEG-2/MPEG-4; ability to connect multiple screens; and as TV output.

Elements of a Graphics Card

Aside In the motherboard interface along with a printed circuit board for a foundation, modern graphics card comprises the following elements:

1. Graphics Processing Unit

A Graphics Processing Unit (GPU) is a dedicated chip that’s optimized to accelerate images. It’s designed to do the basic floating-point calculations for producing 3D images and drawing 2D images. One of the primary features of this GPU is its core clock frequency that translates a 3D picture characterized by vertices and lines into a 2D image formed by pixels.

2. Video BIOS

The Video BIOS, also referred to as the firmware, comprises the basic program that controls the graphics card operations and teaches the computer and applications to interact with the card.

3. Video Memory

Video Memory is used to store many data in addition to the screen image, like the Z-buffer.


The RAMDAC, or Random Access Memory Digital-Analog Converter, accounts for converting digital signals to analog signals which is used by a computer screen which uses analog inputs like Cathode Ray Tube (CRT) displays. RAMDAC acts like a RAM chip that regulates the functioning of the graphics card.

5. Outputs

Graphics Cards and the screen modules have to be connected by some means.

6. Power Demand

Graphics card tend to absorb a large number of electrical energy. Despite efforts to create recent CPU and power supply more efficient, the energy demands of GPUs still continues to grow, thus producing the graphics card that the largest electricity consumer in a pc.

7. Cooling Devices

Of energy, it’s anticipated that some of this will be converted into heat. If the heat generated isn’t dissipated to the air then the graphics card will overheat and in the process be ruined.

To Answer this issue, developers have integrated cooling apparatus that Allows heat to be move elsewhere. Cooling apparatus, a computer lover, and installing a water block.
