it has more bandwith in other can get more performant expansions for say raid cards or more commonly graphic cards
They come with 3 PCI express ports
PCI Express 2.0 x16.
A pci and a pci-e are different ports. I would say no for sure. http://www.whatthetech.com/2007/11/10/can-pci-express-graphic-card-work-in-pci-slots/
PCI express (commonly referred to as PCIe or PCI-e) have taken existing PCI technology and multiplied it. (1x, 4x, 8x, 16x) PCI-e typically has a 16x or 8x multiplier compared to the original PCI transfer rates.
PCI express is faster
PCI Express 2.0 x 16 is the Fastest But PCI Express x16 is faster than AGP
The PCI Express Root Port functions the same way as a regular PCI Express port, with the additional function of monitoring the interconnect hierarchy of the PCI ports. This function includes tracking the interconnect bandwidth and making sure that the PCI port hierarchy is functioning properly
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
A PCI express x16 is faster than an x1. An x16 has 16 'lanes' while the x1 has only 1.
A 16 x PCI Express is better,but you may get a better deal with an AGP card.If you want the very best graphics then you use two 16x PCI express slots running SLI>
The PCI slot is faster. Offer mayor speed because the PCI use more faster BUSes and new architectures. The PCI EXPRESS is the newest version of the PCI architecture.
Yes PCI express 2.1 is backwards compatible
