The only difference is the fact that G0 runs a bit cooler.
There should also be no difference between the Q6600 and X3220. however, i do not believe there has been as significant in price drop for the X3220 compared to the Q6600.
someone else can address the binning question since i am not 100% sure about it.
okey this is how it went according to DDTung, a legend over at XS.
The two chips are identical. But The xeon's used to get Better Bin'd C2D chips when making them. This is not true anymore, so i dont see the need of you guys getting a Xeon over a Q anymore.
My Xeon had a lower start up voltage, which ment it should scale a lot higher in the higher end. The Q had a slightly higher start voltage, which also ment it should overclock slightly worse then the X3220.
My board doesnt like Xeon's for some apparent reason. The 680i had a uber FSB wall at 375FSB-399FSB. Then at 400 it took a rediculous amount of voltage to hold up. Once i dropped in the Q6600, my max voltage went down to about 1.49Vcore on the Q.
The Xeon required 1.51Vcore. Now on the P35 it completely changed. The Xeon3220, is most likely my second best quad. It can go as high as 3.75 dual orthos stable, on the P35, but required voltage at 1.51Vcore to hold it stable there.
If your looking for the better overclocking chip, i would say your best bet is the G0 Q6600. The Xeon's to my last knowledge on XS doesnt overclock as well as they used to anymore. There basically the same draw as a Q6600 in overclocking now.
However i want a Cloverdale :T Wish they made a overclocking 771 board.
If anyone is wondering what my best quad is, its the G0 Q6600 ES.
