What does a video card do?

Question

What does a video card do? Like what is the difference between a geforce 7300 and a 7950gx2? Why is a $500 card better than a $50 card

Answer 1

although it isnt, i like to think of a video card as being like a bi-lingual translator. the better translator u have, the better you'll be able to understand the person on the other side.

a 7950gx2 is a really fast graphics card and in performance it'll look something like this:

7950gx2: 150 fps (frames per second, the higher the #, the smoother the actions on the screen)

7300: 15 fps....

anything below 29.9fps is "not very smooth" to the human eye. also it is not the amount of onboard memory that matters, but the processor that they use on the board. a 512 mb cheap card will get killed by a 256 mb expensive card.

for the 2 cards...there aren't any extra features. they are both gaming cards and are used for that purpose

What Do Video Cards Do

Answer 3

A video card converts information from the computer to something humans can see. The original use was only for text but as computers progressed so did the video card. By using the computers strongest asset, math, programmers began to generate geometry on the screen. Eventually the graphics became so complex that they started placing mini computers or graphical processing units (GPU's) on the video cards. On the low end cards you will find simple computers and small amounts of memory (128 Meg). On more advanced cards you can find multiple processors and up to 1 Gig of memory. There are other benefits to the more expensive cards but the bottom line is, if you are playing intense video games the more processors and memory the better.

Answer 4

A video card is a hardware that enables the central processing unit of a computer to relay video ie moving pictures and still picture to the monitor or screen.

Ever since the invention of the video card, there has been consistent developments or up grading making the more fast and with more capabilities. This is why you ffind them differently named and priced. A $500 card can be better than a $50 card in the sence that it has more components which makes it more efficient hense more costly. You will actuall find out that a paticular card moght not display some pictures where as another can do.

Answer 5

A video card is responsible for displaying images onto your monitor. Without your video card you can't see anything on your monitor, desktops, web pages, etc. Now as far as to why a higher dollar card is better than the other? Well more likely it has more video RAM (RAM installed on the card itself, not pulling from the computer's motherboard memory banks) and also the higher dollar card may have more features than the cheaper one (can allow you to watch TV on your computer monitor, etc) Hope this helps you out.

Answer 6

A video card provides output to your monitor from whatever applications are being run on the PC. All video cards provide enough basic processing power to display the output from standard windows programs, but vary in their ability to process large amounts of video data, such as performing video or picture editing, or gaming. The more powerful the processor, memory, and number of pipelines within a graphics card, the better it can handle high end tasks such as Adobe Premiere, or Quake 4.

Answer 7

the memory of the video card and the brand

Answer 8

the more expensive the video card the better
its what makes it so you can see what your doing on your monitor the more expensive the card the better it can project images esp. during games and watching tv/movies
nVidia makes good video cards i would recomend newegg.com
