Graphical cards are PCB (Printed Circuit Board) hardware cards used to control the output on a display screen. They have their own RAM or ROM and Processor for processing video games. An AGP (Accelerated Graphics Card) is used to integrate a hardware graphical card to your computer's motherboard. The AGP card is a dedicated interface to transfer graphics data. AGP can be classified into different groups based on the speed and signalling voltages; AGP 1x/2x signals at 1.5v or 3.3v, AGP 4x signals at 0.8v or 1.5v and AGP 8x signals at 0.8v. If you have an AGP 4x motherboard then the fastest display card you can use is an AGP 8x graphical card.
AGP, established by Intel in 1996, has dominated the market for almost 10 years. It has made continuous improvements on both their motherboards and graphics cards.
The AGP 1.0 standard is characterized by its speed x1, x2 for transfers ranging from 267 MB/s to 533 MB/s and above, within a voltage of 3.3 volts. This standard was used from 1996 to 1998 and is very compatible with the current AGP graphics cards.
Since then, a few hybrids standards have emerged, such as the AGP PRO characterized with the same transfer rate as AGP 1.0 but is distinguished by its own channel for a strengthened voltage.
Between 1998 and 2002, the AGP 2.0 dominated the market. This standard features a diminished tension; it has a voltage of 1.5 volts and a rapid transfer rate (x1, x2 and x4) ranging from 267 MB/s to 1066 MB/s.
At last, in 2002 and up to now, the AGP 3.0 is underway. In 2007, this standard was characterized by a voltage of 1.5 volts and a single x8 transfer rate of 2133 MB / s. But at the beginning of the AGP 3.0 standard, there were also transfers of x4 and x8, 1066 MB/s to 2133 MB/s with voltages ranging from 0.8 to 1.5 volts...
In addition to these three main, there are many more:
- AGP 1.5 volts
- AGP 3.3 volts
- Universal AGP
- AGP 3.0
- Universal 1.5 V AGP 3.0
- Universal AGP 3.0
The size and format slots for AGP motherboards come in 3 different formats...Some graphics cards will not fit in the slot and others may, but may still not work...
What about my purchase?
It is possible to put a recent graphics card in an old motherboard but it is however recommended to test whether it works or not.
Also if you put an old graphics card on a recent motherboard, it might not work.
But it is without the risk of your equipment crashing.
