Guys! Can someone give me the difference between AGP and PCI express? I'm really confused..Thanks!?

Answer 1

AGP & PCI Express are Vidoe card connections standards.

PCI Express is the newer of the two.

Answer 2

AGP and PCI express are different ports on your motherboard. AGP is older, and PCI express is the new hotness. You are probably trying to pick out a graphics card. If so you need to find out whether your motherboard has PCI express if you want to buy the new stuff. It is a pretty safe bet that your computer has AGP, and is probably the video card that you are using now. Watch out for just PCI graphics cards, those are the oldest, and the slowest. However, by the rare chance your computer doesn't have either an AGP or PCI express port, it will be your only option.

Answer 3

The Accelerated Graphics Port (also called Advanced Graphics Port, often shortened to AGP) is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. Some motherboards have been built with multiple independent AGP slots. AGP is currently being phased out in favor of PCI Express.

PCI Express, officially abbreviated as PCIe (and sometimes confused with PCI Extended, which is officially abbreviated as PCI-X), is a computer system bus/expansion card interface format. It was designed as a much faster interface to replace PCI, PCI-X, and AGP interfaces for computer expansion cards and graphics cards. The PCI Express (PCIe) physical connection (slot) is completely different than those of the older standard PCI slots or those for PCI Extended (PCI-X).

Answer 4

There both buses(data paths) used to transfer data.

AGP was created way back when people needed a way to get graphic data to CPU alot faster then using the old ISA bus which is shared with other things beside graphic cards(ie: Network cards, Modems, Etc)

PCI Express(not to be confused with PCI X) is a new bus that is alot faster then AGP. But unlike AGP it's not just dedicated to Graphic Cards. Even though it shares it bus(data path) with other objects(ie Modems, Network Cards, Etc) it still is faster then AGP. This is because of it's Superior design in using network like scheme(ie Switches) to move data round alot faster.

PCI Express comes in with different types of lanes.. Some mother boards have two 16x lanes for two graphic and Crossfire or SLI support.

Answer 5

PCI X came out a few years ago and was a very important leap in technology because It dramatically increased the availiable bandwith for graphics cards. Newer cards like the Geforce 8 series aren't availiable in AGP because they are too fast for it and AGP is old technology and most computers still around don't have AGP slots. Another BIG leap in technology based on PCIX was nvidia's SLI technology.

Answer 6

PCI express is faster than AGP, that's the big difference. PCIe is also the more popular format. There are more new motherboards and new graphics card in the PCIe format. PCIe cards are also cheaper than comparable cards in AGP format. But the AGP format is still very much alive and kicking.

Answer 7

AGP slots are X8 while PCI-E are X16. PCI-E are newer & have higher bus speed. I don't think any new AGP cards are gonna come now.

Answer 8

They are two different things. Pci-e has a faster buss, but both are OK.
