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.
