Quad Core Q6600 or Xeon X3220

[lemonadesoda]

Both are 2.40 Ghz, with 1066FSB and 8MB cache.

Both are the same price $266.

Which one is the better buy? Are they pin compatible?

What's the difference? Pipeline structures? Cache scheduling? Or just the "register" that allows 2 Xeon CPU's to cooperate on a 2 or 4 socket MB?

Q6600 more chipset options including sli and xfire chipsets. Xeon's don't have that, just the registers you were talking about.

EDIT: Q6600 uses standard unbuffered ddr2. Xeon's use FB-Dimms (buffered)

Besides for the fact that the Xeon 3000 series are socket 775 and not 771. So they use desktop chipsets which don't support FB-DIMMs.

Same price you say? Strange that Xeon Euro prices are still as high as they were before the price cut.
We got:
X3220 @ 480€
and
Q6600 @ 236€

Are they pin compatible?

Yup.

It's the same Conroe die as on desktop CPUs. There's no multisocket support either.
LGA775 Xeons are workstation CPUs just like S939/AM2 Opterons on AMD's side.

why is the q6600 selling for 300+ dollars at the egg?

Darn it, I think I saw Q6600 this morning for $264 at tigerdirect, now it's $289.99!
