Video card or graphics card is a kind of unique computer accessory. Although graphics cards are meant to display superior media files, it is not necessarily required for basic computing tasks like internet browsing or managing office documents. Most of the computers have inbuilt graphics cards to display basic activities. One can even enjoy playing light games with these built-in video cards.
Usually, inbuilt graphics cards tend to share their memory with RAM. These integrate graphics cards include dedicated video memory, but they can’t handle heavy media files, for example 3-D rendering, as that of separate video card. If you are a graphics editor or a pro hardcore gamer, you have to use latest-generation video card that involves a fine amount of dedicated memory on board.
The graphics cards were primarily designed to use normal PCI slot available on the motherboard. After some time, manufacturers and developers introduced a slot that was especially meant for graphics cards, and named as AGP or Accelerated Graphics Port. These modernized ports offer high-speed transfer rate between graphics card and CPU. This revolution has made the gaming performance even better than ever.
The latest graphics port is known as PCI Express x16. It is one of the best dedicated video card slots that allow transfer rates two times faster than AGP. These days, the latest video cards are being manufactured into the PCI Express format. Well, you could still use normal AGP cards, however the PCI Express x16 is currently a leader in the market today.
Some high-class gaming and 3D designer computer systems include multiple video card slots. It allows the user to insert a couple of cards in the system to get much quicker video concert. The inbuilt memory of graphics cards ranges from 128MB to 1GB or more, and it could be DDR or express. Double Data Rate (DDR) memory transfers the data at high speed, about twice as fast as the usual memory.
Video cards are very dominant accessories and come with their own processing system, which is known as the Graphics Processing Unit (GPU). In other words, it is the core part of video card, and it controls all the complex graphics algorithms that generally need to be done by the main processor. The GPU is not rated in MHz or GHz as that of normal CPUs, but each new age GPU assures the quality performance.
Lots of graphics card manufacturers and vendors are in the market today, but two most popular companies are NVIDIA and ATI. NVIDIA offers GeForce series cards whereas ATI has its Radeon family. Few other vendors buy the core cards directly from the two manufacturers and pack them up with other important parts then supply them using their own brand.
Exactly similar core card might involve slight changes and modifications. It depends upon how it is packaged and manufactured. If you need something extra, you can shop around and look for different core cards. Matrox is another good company in this field. Matrox is famous for the video cards that have multiple outputs. It has some real stunning features and you can even stretch your gaming screen over multiple monitors at the same time.
