Video Graphics Card

Graphics card or video grapichs card is an expansion card whose function is to create and display the on-screen displays. This graphics card is comprised of a series of electronics components. Usually embedded in the CPU slot on the main board in the computer. Some cards offer other functions, such as video capture and TV tuner adapter for, describe MPEG-2 and MPEG-4, FireWire, and connects to several screens. Some of the companies that made the famous graphics cards include ATI, Matrox, and NVIDIA.

Motherboard grade class down to the middle class generally have incorporated graphics chipset produced by Northbridge (ie nForce chipset with Nvidia graphics or an Intel chipset with Intel graphics) on the motherboard. Graphics chip like this generally only have a small amount of memory and it will take some memory from the RAM of the total available RAM memory. Graphics chip embedded in the motherboard is usually referred to as the integrated graphics card or onboard graphics card. Graphics chip like this will not result in high performance and support for running 3D applications.

The video card is an interface or intermediary graphics used in computer systems in particular PC, which serves as a medium to convey information to the media viewer or screen monitor or projector. This video card, also known by other names, the vga card (vga card), video adapter, graphics adapter, graphics card, and a video controller.

Basically, the video graphics card is simple. Video graphics card just serves to show only the information from the computer system to the screen. However, for the current video card has changed, not only displays information, but has evolved into a processor or processing information sent computer before being shown to the screen. Moreover, with the development of three-dimensional programs or games that require complex data processing.

The video graphics card was introduced by IBM that is used on the IBM PC was developed in 1981. At that time, known as MDA (monochrome display adapter) that can only work on a fashion show or text that describes the 80 colom and 25 rows. This video card has only 4KB of memory and works only with one color. After that, there developed a wide range of video cards.

Some companies also come into play in developing and issuing these video cards like ATI, Cirrus Logis, and S3. They compete to develop and improve the performance of this video card. The increase in the extent of resolutions that can be displayed on the screen and the number of colors that can be displayed.

VGA (Video Graphics Adapter), is an analog computer display standard first marketed by IBM in 1987, although the VGA standard is no longer used because it has been replaced by a newer standard. VGA is implemented on the Pocket PC. VGA was the last graphical standard followed by the majority of the computer's graphics card manufacturer seen from its name is the main function of this component is to process everything related to graphics or display of the operating system (Windows, Linux etc) to be displayed back to your screen.

This component also connects the computer to the monitor so that the digital image signal can be transformed into something that we can see and understand. Using a computer that does not have a VGA card is the same as using a computer with eyes closed, and typically the computer will not be able to live without this VGA card. Component form is simple, just a circuit board with several ICs which usually have either aluminum cooler with the fan or not.

Many types are offered in the market right now, but in general can be grouped into two parts. The first onboard graphics card or integrated graphics card or an add-on extra. Onboard graphics card is an economical solution that effectively and efficiently for computer users, because they do not need to buy a graphics card or add a pretty good value in the CPU, because the graphics card has been integrated on the mainboard of the computer.

There are two typical onboard graphics card in the world, one that has had an embedded RAM memory on the mainboard (mainboard type is rare in the market because prices tend to be more expensive than an identity card mainboard onboard graphics usual). The second is an onboard graphics card that takes memory from the computer's main RAM, it's an identity card kebanyakkan from mainboard onboard graphics in the market because it is cheaper than other types of mainboard. While the add-on graphics card is a separate graphics card and should we add on our computer. The graphics card of this type are generally expensive and have a much better performance than the onboard graphics card kebanyakkan.

Well, for those of you who are crazy about the game 3-dimensional or need a powerful graphics card performance such as the use of video editing program or a program of 3-dimensional, not one choose make sure when you buy a computer equipped with a graphics card add-on is not just the onboard alone .

There are two big companies are always competing and claiming that the add-on graphics card homemade is better, the company is nVidia and ATI. Although in the market we can find a lot of brands but we can be sure that the main IC chip or artificial surely one of the following is an example of the comparison between the two VGA add-on, congratulations comparing hopefully you can choose according to the needs and requirements in using the pc you.

* AMD HD3D - This is one of the new features brought by AMD Radeon HD 6000 Series. With this feature, the AMD Radeon HD 6000 Series is capable of displaying games and movies in 3D format. At Catalyst drivers 10.10, AMD has enable support Blu-ray 3D and this feature only runs on AMD Radeon HD 6000 Series.
* UVD 3 - UVD (Unified Video Decoder), a graphics card features AMD (ATI) that allows the graphics card do the decoding video / film. Usually the process of decoding is done in the processor. The advantage is that the processor is no longer burdened with the task of decoding the video and can perform other tasks. In UVD 2, this decoder supports VC-1, H.264, and MPEG-2 (IDCT Profile). While in UVD 3, in addition to the UVD 2 format, other formats supported are Multi-View Codec (Blu-ray 3D), MPEG-2, MPEG-4 part 2 (XviD / DivX).
* HDMI 1.4a - the AMD Radeon HD 6000 Series, HDMI has been revised to version 1.4a. HDMI 1.4a allows the AMD Radeon HD 6000 featuring a variety of content in 3D formats such as Blu-ray 3D.
* AMD Accelerated Parallel Processing (APP) Technology - It was not the latest feature from AMD (ATI). Previous feature is called ATI Stream. This feature allows non-gaming applications to run on the graphics card, is no longer on the processor.

Until now, the NVIDIA GTX 580 graphics cards remain a dream as well as a target gamers and casual users. This is reasonable because the NVIDIA GTX 580 single-GPU graphics card terkencang currently able to offer the convenience of playing games on setting the image resolution and the highest quality graphics. Although single-graphics card throne terkencang has taken NVIDIA GTX 590, NVIDIA GTX 580 remains one of the best options for single-GPU graphics card has better game compatibility than dual-GPU graphics card.

Various advantages of the NVIDIA GTX 580 graphics card would make manufacturers keen to present a special edition NVIDIA GTX 580. To date, several manufacturers have presented a special edition GTX 580 NVIDIA them and we feel good because some of them have had our review. NVIDIA GTX 580 offers a special edition usually be some advantages such as higher clock specification, 3rdparty HSF, quality components, even those that provide attractive sales package.
