What is the advantage of having memory in Graphics cards? - what purpose does it serve?

Question

please answer :)

Answer 1

Leaves the Visual Field Processing to one area;
For a similar reason the Game Consoles like the XBOX 360s have 3 Processors, each with dedicated areas; The Graphics Card works on the visual Side, and it needs its own memory so, instead of stealing from the central processors, it is given its own

Answer 2

In the old days, all graphics processing was done by the CPU using on-board RAM. And graphics back then wasn't that demanding, less than 15 frames/second.

With the advent of Windows and other GUI operating systems, graphics became much more demanding and slowed the computer way down.

So the graphics manufacturer's added a graphics processing unit (GPU) and, later, video ram (VRAM) to their cards so the system CPU and RAM wasn't used.

As a result of that, frame rates in the hundreds/second are now possible with virtually no loss in PC performance.

Answer 3

Since Windows is a Gui (Grapical User Interface)

Speed to display screens is important,
The memory of a graphics card takes the pressure off the
normal ram / main board processing, since the card can access its own ram directly. Ie for displaying a screen/window in the background quickly to the foreground. And / or diplaying HEAVY graphics on the screen.

Answer 4

"Graphic Card" also known as a "Video Card" generates and displays images from your computer. Video cards are connected to the motherboard, and they either use the computer's RAM or their own RAM (VRAM). The point of having a memory card with higher memory is so that images and 3d graphics display better on your monitor. Most video games nowadays recommend a 256MB card, as it is more powerful than the 128MB card most base-model computers are sold with. Computers can handle 2 video cards in some cases, where each of the video cards handles half of your monitor. The greater the graphics card is, the better images and games will look on your computer.

Answer 5

It offloads processing from the CPU. Every time a graphics card polls the CPU to move data from standard RAM, it takes time and uses CPU ticks. If the memory is on the card, the CPU doesn't get polled so much becasue it can dump larger chunks of data at a time, so it isn't switching back and forth.

These days, most video cards already have CPU of their own. Then, all they have to do to get data from storage is to use the bus architecture to fetch it. This saves a lot of CPU ticks too.

Answer 6

All GPUs run better, faster, as does the central processor unit, when there is sufficient memory onboard to fully process the visuals.

This is not simply limited to Microsoft's very meagre system of "windows".

This is true in Sparc, SGI, Alpha, MacIntosh, Amiga, systems, and the 800+ Unix or Unix clones that do the real fast and wonderful graphics you see in advertising, and on the Internet. Check out the Beryl or Compiz visuals, in Google, and on Youtube, with key search word "linux", "Linux 3d", "Beryl", or "Compiz".

With *BSD and GNU/Linux systems running upto 50X faster, and being FREE to download, you really need to try one of the http://livecdlist.com 310 free distros!

Answer 7

*having memory in your Graphics cards means you are not using your computers memory so it dose not slow are computer down

Answer 8

The computer will run better.It will not take RAM from the main Compueter.So it runs faster.

Answer 9

Then it doesn't suck from your ram.
