How to choose an adequate graphic card

A graphics card is mainly composed of a processor, GPU (Graphic Processing Unit), and memory.

The graphics card is in itself a small PC dedicated to graphics applications, independent of the rest of the PC, the only link being the information passing through the port graphic and food.

Choosing a card is based on its needs and its budget:

  • For desktop applications, a map called "entry level" enough;
  • For multimedia applications, a map can read the desired video format is imperative;
  • For 3D video games (and generally all 3D applications), one more powerful is essential.

Structure of a graphics card

The essential component that will determine the performance of the graphics card is the GPU:
A modern GPU is based on different units calculation:
  • Processors Flow
  • Texturing units,
  • Raster units (ROPS).

The most important are the processors flows over the number of processors flow is important, the GPU will be more powerful (for architecture).
The model number on the card is linked to the GPU.

To enable the GPU to store its calculations, there are memory:
  • It varies in quantity:
    • 256 MB enough for the tickets range of previous generations;
    • 512 MB is sufficient for most current cards graphics;
    • 1GB is needed for cards with a very powerful GPU, the GTX 280;
    • Broadly speaking, the more you play in high resolution and filtering enabled, you need more memory.
  • It varies in type:
    • DDR2, DDR3, DDR4 or DDR5: The higher the figure, the greater the memory is fast. His type does not relate to that used for RAM PC: you can have a PC in DDR2 and DDR3 graphics card.
  • Its frequency:
    • Plus it is high, the card is more powerful.

Finally, to link GPU and memory is the memory bus.
The width of this bus is important: it may be 64, 128, 256, 384 and 512 bits: over the bus is large, most trade between the GPU and memory will be rapid. A map to 256-bit bus is efficient at a map of 128-bit bus for the same GP

HOW TO FIX ERROR 80070002


The problem is with your graphic card G33/G31. Since its an Integrated graphic card you need a dedicated GPU to run games on decent settings.Earlier i had the same graphic card and i can only play games from 2005.This GPU is too weak to run such games. I suggest you to buy a new dedicated graphic card.

my current video memory is 119 but max is 762. how do i increase it to max


If you are using a laptop the video card probably uses what is called shared memory for the Graphics Processor. Which means it pulls RAM from the system and uses for processing graphics. Typically the computer controls how much RAM to dedicate to the Graphics Processor. More RAM is always good. I would check in my BIOS. Sometimes they put RAM allotment for the GPU there. If they advertised that you can get a total of 762MB out of your GPU then it wouldn't surprise me. Just remember the more you dedicate to your GPU the less you have for your system.

hi sir i have asus p5 nmx having nvidia geforce 7050/nforce610i integrated graphic .it shows 390 mb total graphic memory in win 7with 1 gb ram .where it shows 780 mb useable ram .here i have chosen 256 mb buffer size from bios .so plz tell me how much graphic memor and use able memory it will show when i will use 2gb and 4 gb ram.


512 for 2gb and 780for 4gb

in intergrated gpu,s the memory is borrowed from the main system memory however the actual intergrated gpu has some of its own memory,but this is normally only small such as 64mb or 128mb however it can borrow memory from the main system memory,something thats known as s.m.a(shared memory architecture)
there are also some dedicated graphic cards that borrow memory from the main system memory,these are known as "turbocache" with nvidia based cards and "hypermemory" with ati radeon based cards,however these cards are very rarely used now as they were not that efficent and in windows vista they score very low performance baseline scores

What are the hardware requirements for this motherboard in the way of memory, and graphics card? I have a pc2700 256M chip that is only seeing 191M of the total ram. Does it require ddr pc2100 instead? And is the AGP 4X or higher? Thanks Jeff


Jeff, some of the system's ram memory is being borrowed. If you are using Integrated Graphics, this is where it is going.

[Integrated Graphics is also known as OnBoard Graphics.
On the motherBoard.

The GPU is soldered to the motherboard. (Hence you plug the monitor cable into the motherboard, via a VGA connector,

http://en.wikipedia.org/wiki/VGA_connector )

A dedicated graphics (adapter) card has it's own GPU.
(Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU ]

Integrated Graphics uses some of the system's resources. The Processor, and Ram Memory.

A dedicated graphics card has it's own Processor, and Ram Memory.

PC2100 is DDR Sdram that operates at a frequency rate of 266MHz.

PC2700 is DDR Sdram that operates at a frequency rate of 333MHz.

http://en.wikipedia.org/wiki/DDR_SDRAM

[Frequency Rate:
Proper 'computer speak' for Speed.
'Speed' is slang.

DDR Sdram:
Double Data Rate Sdram
Synchronous Dynamic Random Access Memory

MHz.
MegaHertz
Mega = Approximately 1 Million
Hertz stands for Cycles per Second.

PC2100 can operate Up To a frequency rate of 266 Million Cycles per Second.
PC2700 - 333 Million Cycles per Second ]

No, using PC2100 is going backwards, and will not help increase the Amount of ram memory, seen by the computer.

According to eMachines Support, the T2642 desktop computer's motherboard, uses an Intel 845GV motherboard chipset.

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T2642

[Chipset, and Chip are slang terms for I.C.
Integrated Circuit.

The motherboard chipset used for the technology of the T2642 motherboard, is the Northbridge, and Southbridge chipset.

(Motherboard's for the Intel Core i3, i5, and i7, do not use this motherboard chipset technology)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Memory Slots = Ram Memory slots ]

The Northbridge chip handles the faster processes of the computer.
The Processor, Ram Memory, and high speed graphics.

High speed graphics being AGP, or PCI Express.
Not a graphics card inserted into a PCI slot.

Integrated Graphics, or a graphics card inserted into a PCI slot, is a slower process of the computer.

Slower processes of the computer are handled by the Southbridge chip.

(At the end of the Northbridge article's first sentence, you will see - southbridge, in blue.

I have a mobo C51PVGM-GB that I would like to upgrade the video card and not use the one built into the Mobo.


You are upgrading the graphics.
Instead of using Integrated Graphics, you will be using a dedicated graphics card.

Integrated Graphics is also referred to as OnBoard Graphics.
On the motherBoard.

The GPU (Graphics Processing Unit) is soldered to the motherboard.

It is not a video (Graphics) card.

A dedicated graphics adapter card has it's own GPU, and graphics ram memory.
