PCI-E vs PCI-X?

[Carlosinfl]

Can someone please explain this to me? How do they differ? I tried just a basic Google and did not find much info so thanks for any point in the right direction.

they are the same thing PCI-Express....

Actually, no, they are not...

PCI-E (or PCIe) is the PCI Express that we are all now used to talking/hearing about, while PCI-X stands for PCI eXtended.

(BTW, this was my Google search for PCI-X....)

No they aren't!

PCI-E is PCI Express, which is newer technology, whilst PCI-X is Extended PCI, which is and improved bandwidth and backward compatible variant of the old PCI bus/slot standard.

The two are NOT compatible!


Edit: beaten!

Back in 2001 when PCI-X was out, it was as fast as AGP 4x. We knew that AGP would be on the outs then. But they are not the same thing, but they use very simular language.
