What is both the physical and other differences of a PCI video card or a AGP video card?

Question

PLEASE!!!TELL ME!!!

Answer 1

Bandwidth and physical pin differences. Plus, to add to the confusion, newer machines also have the PCI Express ( PCIe ) bus, not to be confused with the older PCI bus which other peripherals still use.

In order of bandwidth, PCI, then AGP then PCIe.

Answer 2

Not to confuse PCI-Express with PCI
First came the PCI devices, in the era of the pentium 1
Then the AGP bus appeared, it was intended to be dedicated only for graphics card. The first AGP bus version doubled the performance of the PCI slot. AGP 2X, 4X, 8X appeared later, on that order, multiplying the data transfer in that ratio exactly.
Then came the PCI-Express which doubles the performance of the AGP.

by performance I mean data transfer speed. Since If you put a old slow AGP card into a machine, maybe a more modern faster video card PCI could do a better job. Today, you'll find just a few PCI video cards, while AGP is still in process of being replaced by PCI express cards.

You also may be interested in SLI, which it consists on using 2 video cards at the same time and in most cases almost doubling the performance. Of course, SLI enabled motherboards have to sport 2 PCI express slots.

Answer 3

Hi. Mostly in the slot into which each goes. The AGP slot is offset back from the PCI slots. The performance depends on the individual GPU.

Answer 4

pci is ok but agp is much better and faster but if you want a real good one go with pci express it is the newest vid. cards and a whole lot faster and better.
