What is the difference between pci express agp pci and sli video cards?

Answer 1

PCI- E, AGP and PCI are the different slots on your motherboard that the graphics card can go into, and different GPUs fit in one of these slots. PCI - E is the fastest port at the moment, so AGP and PCI video cards are declining. All computers have quite a few PCI ports but most modern motherboards have PCI - E ports and not AGP. If you are buying a GPU, you will need to check what ports your motherboard has, so you know it is compatible. SLI is nVidia's dual graphics card system, and only selected motherboards support this. An SLI compatible video card can be used together with another SLI compatible video card in an SLI compatible motherboard.

Answer 2

A couple of years ago there was PCI and AGP. AGP (Advanced Graphics Port) was used to install graphic cards, while PCI was generally considered to be too slow (back then). PCI stands for peripheral component interconnect and was designed to work with any type of component (plugged into the slots of the computer), while AGP was designed to work specifically for graphics use only. Later, PCI express (PCIex) we developed offering much higher data rates and it soon became a viable alternative to AGP. Today, AGP is an old standard that's outdated and used only in old systems. The up-to-date standard is PCIex.

Answer 3

An AGP graphics card utilizes an outdated and relatively slow slot on the motherboard. PCI-Express is the much more modern slow on almost all new PCs nowadays and is considered much faster. New graphics cards mostly all of have PCI-Express x16 slot cards.
