No, they are completely different. PCI is a general purpose card interface, AGP is specifically for video cards. Most often you will see an older machine that has one AGP slot and several PCI slots.
Both PCI and AGP are out of date, you won't see any new motherboards or computers with AGP, and PCI is in 'legacy' status, that is, PCI slots are only included on motherboards to support older cards that the owner might have.
The modern slot is PCI-e (which is incompatible with the older PCI)
No AGP is older and slower. AGP was superseded PCI Express in 2004.
PCI, PCI-e, AGP
Its either shorter than pci or longer than pci and agp Its either shorter than pci or longer than pci and agp Its either shorter than pci or longer than pci and agp
PCI express is about twice as fast as AGP and will ultimately replace AGP.
The PCI Express x16 is intended to ultimately replace the AGP bus along with the PCI-X and the Conventional PCI.
No. There's a reason there's AGP and then there's PCI-E..
PCI PCI Ex 16 AGP
It's safe to say that agp has already been replaced by pci express.

The PCI video card should work, but you may need to change a setting in your BIOS to recognize it. Enter "setup" when the computer starts, and look for a setting about video options. There is usually a setting indicating to seek an AGP or a PCI video card upon startup. NO! A pci video card will only fit into a pci slot in a motherboard. Likewise an agp will only fit into an agp slot. They are completely different. Both of these above answers are right and wrong. PCI and AGP are two totally different standards, but as long as you have an open PCI slot, you can use a PCI video card and opt not to use the AGP (Make sure to change appropriate options in your BIOS.) ==Answer == Yes you can use a PCI card where the slot is avaliable, but if your motherboard has a slot for AGP cards it is worth noting that the systemboard was designed with AGP in mind. It offers a system bus direct to the prossesor for faster unhindered communication.Running a PCI card on a AGP board may and probably will slow down your system performance.
