PCI-X is not PCI-E

[Brent_Justice]

I'm so tired of people confusing the two all the time, i see it everywhere now.

Sorry, had to rant.

 

[obs]

So when are PCI-X motherboards coming out?

 

[Elledan]

One might think that no one except for small minority has even a clue that there exists such a thing as 64-bits PCI, or PCI-X.

Fear the 'Does it have PCI-X?' type of questions

 

[mcryptic]

just call pci-express 3GIO, it sounds better anyway

Since when is it PCI-E? It's PCI Express.

PCI-E for short, or PCIe sometimes you'll see it that way too

PCI-X is for servers(and a bit slower IIRC),
and PCI-Express is for home PCs

Was a joke.

This deserves a sticky

Correct me if I'm wrong, but I'm pretty PCI-X is faster, it at least has more bandwidth... at least compared to the PCI bus that's in most of our systems. Not sure how it compares to PCI Express, though.

If I remember correctly, PCI X is 64bit 66MHz.
PCI is 32bit, 33MHz.
PCI E is scalable.

pci-x can actually run at 100, 133, 266, and 533mhz as well.

thanx for clearing that up. and i agree that this should be stickied

Are you positive? I believe its actually 66, 100, 133

 

[xonik]

It's 133 MHz base frequency, with two samples per clock cycle (266 MHz) and four samples per cycle (533 MHz). These double and quad data rates were added in the PCI-X 2.0 specification.

yes, i said as well as...

its starts at 66mhz

he was saying PCI-X was slower than PCI-Express, not that it was slower than vanilla PCI.

I'm pretty sure that PCI-express will be used in servers too for things like gigabit lan.

Naw, 64-bit/66 MHz PCI or PCI-X is more than sufficient for this task. There already are a plethora of Gigabit expansion cards for servers/workstations.
