What To Know
- However, if you are on a budget or if you have an older motherboard that does not support PCI Express, then AGP may be a better option.

- PCI Express is a serial bus that is used to connect a variety of devices, including graphics cards, sound cards, and network cards.
In the world of computer graphics, two main types of expansion cards have been used to connect graphics cards to the motherboard: AGP (Accelerated Graphics Port) and PCI Express (Peripheral Component Interconnect Express). Both AGP and PCI Express have their own advantages and disadvantages, so it’s important to understand the differences between them before making a decision about which one to use.
AGP Video Cards
AGP was developed by Intel in 1997 as a replacement for the older PCI (Peripheral Component Interconnect) bus. AGP is a dedicated port that is designed specifically for graphics cards, and it offers several advantages over PCI. First, AGP provides a higher bandwidth than PCI, which means that it can transfer data between the graphics card and the motherboard more quickly. Second, AGP supports sideband addressing, which allows the graphics card to access the system memory directly without having to go through the CPU. This can improve performance in some applications, such as games.
However, AGP also has some disadvantages. First, it is a proprietary technology, which means that it is only supported by Intel motherboards. Second, AGP is a legacy technology, and it is no longer being developed. This means that there are fewer AGP graphics cards available on the market, and they are often more expensive than PCI Express graphics cards.
PCI Express Video Cards
PCI Express was developed by the PCI Special Interest Group (PCI-SIG) in 2004 as a replacement for AGP. PCI Express is a serial bus, which means that it uses multiple lanes to transfer data. This allows PCI Express to achieve much higher bandwidth than AGP. PCI Express also supports hot-plugging, which means that you can add or remove PCI Express cards without having to turn off your computer.
PCI Express has several advantages over AGP. First, it is a more modern technology, and it is still being developed. This means that there are more PCI Express graphics cards available on the market, and they are often less expensive than AGP graphics cards. Second, PCI Express is more versatile than AGP. It can be used to connect a variety of devices, including graphics cards, sound cards, and network cards.
However, PCI Express also has some disadvantages. First, it is more complex than AGP, and it can be more difficult to troubleshoot. Second, PCI Express requires more power than AGP, so it can put a strain on your computer’s power supply.
Which One Should You Choose?
So, which type of expansion card should you choose for your next graphics card? If you are looking for the best possible performance, then PCI Express is the way to go. PCI Express offers higher bandwidth and more features than AGP, and it is the future of graphics cards.
However, if you are on a budget or if you have an older motherboard that does not support PCI Express, then AGP may be a better option. AGP graphics cards are still available, and they can provide good performance for a lower price.
AGP vs PCI Express: A Comparison
Here is a table that compares the key features of AGP and PCI Express:
| Feature | AGP | PCI Express |
| — | — | — |
| Bandwidth | Up to 2.1 GB/s | Up to 16 GB/s |
| Sideband addressing | Yes | No |
| Hot-plugging | No | Yes |
| Power consumption | Lower | Higher |
| Price | Lower | Higher |
| Availability | Limited | Widely available |
Wrap-Up: AGP Video Card vs PCI Express
Ultimately, the best way to decide which type of expansion card is right for you is to consider your own needs and budget. If you need the best possible performance, then PCI Express is the way to go. However, if you are on a budget or if you have an older motherboard, then AGP may be a better option.
