They are part of the better binned chips. Higher reliability, higher resistance to heat, etc.

Better binning, tighter specs, and longer guaranteed availability.

They're not that much more expensive. Hardly any difference between the i7 920 and the W3520(?) in UK.

In a word: yes.

They meet higher standards and support ecc memory. Server processors are also able to run on multi socket mainboards, where workstation processors (and desktop processors) will not.

i7 920 <-desktop processor
Xeon W3520 <-workstation processor
Xeon X5550 <-server processor

like others said, they are binned higher, and usually overclock better than the regular i7's

W series Xeons are very close or equal to their i7 counterparts. All the Dual QPI series are more expensive than an equal i7 (E,L,X)

*Edit; And I think that Intel price gouges on the dual QPI Xeon's because they are targeted for companies buying for servers with big budgets and not desktop users. All 1366 i7's have dual QPI's and Intel goes out of their way to disable it on the i7's and W xeons btw.

This. Wish we could enable that feature though LOL

Because people will pay it.

Intel Xeons are not the same as AMD opterons. They are not better binned or better clockers. They are merely restamped as Xeons.

Actually it's the other way around. There are far more Xeon models than there are equivalent desktop models.

Take a Xeon, "castrate" it (remove one of the QPI links or slow it down, the ability to install in multi-sockets, etc) and you get your consumer / pro-consumer equivalent.

I would disagree with the statement that they're not better binned - but short of having direct physical access to the manufacturing process, there's no real way to claim one way or the other.

Uh... what? Xeon's (even the W versions are made on different wafers.) They have different memory controllers and error checking and such.

I had a I7 920 that couldn't do 4.0 ghz @ 1.3-1.35 vcore. I got my Xeon that does 4.2 ghz @ 1.288 vcore. Both 939 B batches. I'd take a xeon any day of the week over the desktop series.

Regardless of the physical differences... Xeons are required to be avaliable longer. The distributors are required to buy extra and store them in case a server needs a replacement down the road. If a server goes down, you do not want to risk changing a component with the risk of minor differences affecting your processes. This extra cost of storage and supply risk is passed onto the consumers.

I don't think so no. Not unless it's available for less money.

If its the same price then IMHO YES.
