Find out the make and model of your Motherboard,
Then check on their website to see the specifications of it and see what expansion card slots it has.
pci express (PCIe)
AGP PCI Express
No. You will need to replace your motherboard to get PCI-E.
no. only on a pcie slot. buy a mainboard with such
No I don't think so. PCI-X is older than AGP which is older than PCIe
Unless it's a very old computer, your graphics card will be either PCIe (PCI Express) or AGP, and if it was bought within the last... Say, four and a half years, it will definitely be a PCIe setup for graphics with your other component cards running on a PCI bus. If it was a gaming computer sold post-2003ish it will also have a PCIe bus.
PCIe (Peripheral Component Interconnect Express)
Express. Peripheral Component Interconnect Express to be complete. PCI-E (or PCIe) is the replacement of the old PCI, PCI-X (often confused with PCI-E and AGP bus interface on computer mainboards.
PCI, PCI-e, AGP
Sometimes PCI, PCI-E, AGP and other slots on motherboards are color coded... but often they are not. If they are different colors, it is usually just that different slots are different colors on the mother board in question. But there is no color coding standard among mother board makers in general.
This is a kind of trick question because there are actually two graphics-only technologies. One could argue the second is only a version of a larger architecture. But, it is "A separate connector used exclusively for graphics", so I leave the semantics up to you. The short answer(s): AGP (for the purists) AGP and PCIe 16x (for the practical) The long answer: The original graphics-only architecture is Accelerated Graphics Port or AGP. AGP was created to enable video data transfer rates higher than PCI video cards. AGP technology advanced over time, resulting in four different modes: AGP 1x was the 1st, transferring data at 266MBs per second. AGP 2x transfers data at 533MBs per second. AGP 4x transfers data at 1.07GBs per second. AGP 8x, the final AGP, transferred data at a whopping 2.14GBs per second. Quite an improvement over PCI. The other graphics-only port is now in the process of replacing AGP. AND it's "back to PCI" (sort of). PCI Express x16 transfers data at 4GBs per second, effectively doubling AGP 8x. The possible controversy: PCI Express slots come in PCIe x1, x2, x4, x8, x16. All except PCIe x16 slots are used for many things. PCIe x16 is used exclusively for video cards and has its own connector.
The three main types of expansion slots are PCI (Peripheral Component Interconnect), PCIe (Peripheral Component Interconnect Express), and AGP (Accelerated Graphics Port). PCI slots are older and used for various expansion cards, while PCIe, which has largely replaced PCI, offers higher bandwidth and supports multiple lanes for faster data transfer. AGP was specifically designed for graphics cards but has become obsolete with the advent of PCIe. Each slot type varies in speed, compatibility, and intended use.
