Technology in VGA

Expansion
This is often and more accurately referred to as the VGA card.PC components this one has its own processor too. Called a GPU (Graphics Processing Units) by nVIDIA, and VPU (Visual Processing Units) by ATI.
It was equipped with a video memory is completely separate from RAM on the motherboard.In most video card products, using a type of RAM is one step ahead of the RAM the motherboard.
Integrated
Integrated on the motherboard, often called the integrated graphics controller. Average have a lower 3D performance, compared to expansion card.This applies, if to compare their performance, with the era and the same class.
The main cause is mostly using the relatively cheaper chipset, to reduce costs.Most integrated graphics controller also uses Sharring system memory, unlike the expansion card that has a dedicated memory.
VGA Glossary
So many that must be considered in the purchase of a VGA card.Because it of its complexity, the components of this one includes three components terumit have in your PC.
Here we include the latest range of specification data from the two manufacturers of graphics controller, ATI and nVIDIA.Start of the series ATI RV370 to R520 that can be found on its X1800 series.As for nVIDIA ranging from main-stream series GeForce 6200 product line up to high end GeForce 7800.Everything is a data specification standard reference board from the chipset maker.While the VGA manufacturers themselves, often make repairs and change the clock settings.With the aim of giving an additional performance on its VGA products.
So many terms in the specification of a video card.What does it mean and which ones need attention?
Architecture GPU / VPU
Is the code of the GPU / VPU that is used on video cards are concerned.VPU (Visual Processing Unit) a term often used by ATI, nVIDIA while calling it a GPU (Graphics Processing Unit).Usually the sequence of numbers behind it based on the chronological time of the development or improvement in technology and performance.In some cases, there could occur due to generation leaps one thing and another.
Manufacturing Process
Just like the CPU, GPU / VPU made in the production process continues to shrink, as the development of technology.Among others, to suppress the production cost, increase the number of transistors (transistor count) in a limited space without adding significant heat energy during operation.In accordance with the development of process technology has been mastered.
DirectX Support
DirectX is a command programming API (Application Program Interface) used by Microsoft.It will be (slightly) easier for game developers work.Well as minimize the problems of comparative tibilitas hardware to the operating system is concerned.
By relying on collection of orders is available on the DirectX standard, then almost certainly as long as compatible with Windows, the hardware in question will not have problems.Seiiring air-added version of DirectX, it also comes with a new special instructions.Which only the latest hardware-hardware as well.It's good to make sure the VGA card that is used to support the latest version of DirectX (DirectX 9.0c version for a while)
Bus Interface
Since its arrival in 2004 PCIe x16 ago, the presence of AGP was already threatened.Initially the data bandwidth of PCIe x16 with 4GB / s which, when compared to 2.1 GB / s on AGP 8x be the main reason.
Since the development of (re) use of dual VGA, reinforce the direction of development of the next video card.As you can see, most new products have been rare or even without including the version with AGP interface slot.
If the motherboard you are using does not have availability for PCIe x16 slot, then the option to upgrade the video card would be a bit limited.Two of the largest manufacturers of both ATI and Nvidia have a tendency to no longer produce the latest video card chipset with AGP slot.Especially if you are interested to make use of dual VGA.Both the ATI CrossFire and nVIDIA SLI, they can only be realized on a particular motherboard that already use the PCIe x16 slot.

VGA Onboard and Add-On

Onboard graphics card is an economical solution that effectively & effectively for computer users, because it does not require to buy a graphics card or add a precious lovely in to its CPU, because it's integrated graphics card on his computer mainboard . There's typical in the world onboard graphics card, that has an embedded RAM memory on the mainboard (mainboard type is never present in the market because the cost tends to be more pricey than the onboard graphics mainboard that with usual card). 

Onboard VGA function 

The second is an onboard graphics card which takes the computer's main memory of RAM, this is a carded mainboard were mostly from the onboard graphics in the market because they were cheaper than other types of mainboard. Because these types of onboard graphics card takes memory from the computer's main RAM. So, usually the size of our computer's RAM will be reduced by the amount used the onboard graphics card. So don't be surprised if the RAM on your computer that ought to not indicate the size, perhaps only because the unused part as an onboard graphics card memory for your computer. 

While the add-on graphics card is a separate graphics card & ought to they add to our computer. Graphics card of this type are usually pricey & have much better performance than the onboard graphics card; most. Well, for you are infatuated with 3-dimensional games or require a reliable performance graphics card such as the use of video editing program or a three-dimensional program, do not choose be sure when you buy a computer equipped with add-on graphics card is not the onboard only . 

Do not forget also determined the performance of graphics cards with large memory & speed of the graphics card. Most people will pay more attention to the graphics card memory size, because usually the more memory then the speed was higher. For onboard graphics card they can basically alter the size of this graphics card memory of the settings in the CMOS (BIOS), but keep in mind that the main RAM is used by your computer tablets. 

As for the graphics card add-on they can only resize it by replacing it with a brand spanking new, surely with a hefty cost, a fair to get better results khan. 

There's large companies are always competing & claim that the add-on graphics card homemade is better, the company is nVidia & ATI. Although in the market they can find lots of brands but can they be sure that the main IC chip or artificial definitely of those large companies.

About Graphic Card

Its name varies. Sometimes they are familiar with the name of the graphics card, video card, video board, video adapter, video accelerator, display adapter, video adapter, graphics accelerator, or a graphics adapter, VGA card but the term is more widely used, both in the user's PC or seller or some producers. However, all refer to a part similar to the primary task of doing the conversion of digital knowledge contains a logical representation, a signal containing visual knowledge to be displayed on the computer screen.

In most cases, used as the display is the monitor, be it conventional CRT monitors (Cathode Ray Tube) monitors and LCD (Liquid Crystal Display). Still included in the display is the use of projectors, or TV as an alternative to the monitor.

Function of VGA Card

Judging from its name is the main function of this part is to to process everything related to graphics or display of the operating system (Windows, Linux etc) to be displayed back to the screen of your monitor. This part also connects the computer with a monitor so that the digital picture signal can be converted in to something they can see and understand. Wearing a computer that does not have a VGA card is tantamount to using the computer by closing the eyes, and usually the computer could not live without this VGA card. The shape of this part is simple, a circuit board with several ICs that usually have either aluminum cooler with fan or not.

Many types are offered on the market today, but usually can be grouped in to parts. The first is onboard or integrated graphics card and graphics card add-on or additional.
