PCI Express Graphic Cards
Even though AGP is not quite a dead technology yet for graphic cards, the trend is quickly moving toward the PCI Express graphic cards. The motherboards which support the PCI Express have a large part of data bandwidth allocated to these new cards that are more often than not divided in 20 lanes.
Sixteen of these twenty lanes are dedicated slots for the PCI Express. Even though there is not a visible expansion of the PCI Express cards, they will definitely begin to be increase this year.
The Pentium 4 and Athlon 64 support the PCI Express graphic cards but additionally they still have the traditional PCI slots that will more often than not choose between PCI Express graphic cards or AGP. Very few motherboards support the PCI Express graphic cards and the traditional ones at the same time.
The main advantage of the PCI Express graphic cards is their immense capacity of future expansion regarding the data bandwidth. On the other hand, the AGP almost reached the limit in their technology. The PCI Express graphic cards have two tricks, one for the low end of the market and the other one for the higher end of it. It will thus satisfy any need of performance and budget for every user.
