Intel's First Nehalem Cpu-Z Pic.

[Blauhung]

Care to speculate on overclocking potential? Will it be slightly better or worse do you think with integrated PCIe??

I would venture a guess that the locked multi intigrated PCI mainstream chips will not overclock nearly as well as we are seeing right now with the current mainstream offerings.

First off, the community currently has no idea how well the new QPI will scale. of course with high multipliers against the QPI, there is the possibility it won't need to scale much, but that's up in the air right now. Second, we don't know how the memory speed will be linked to the QPI speed and there could be another point that hinders the available headroom. Both of these factors will hit all of the Nehalem type chips.

For the mainstream ones, you take the above mentioned unknowns and tack on integrated PCIe, there's another portion of the same die that will have to somehow recieve a clock signal. It's possible that this core clock signal is also based off of to the QPI frequency, so if the headroom on the PCIe portion of the chip may end up being a limiting factor.

There are many ways that all of these can be handled, but I believe that the mainstream side of things will take the tact of simplicity over tweakability.

Edit: although, i think we must keep in mind, even though they may not overclock as well, they will be faster then their penryn equivalents. The question becomes, is there enough headroom on the mainstream chips to put a maxed out mainstream Nehalem (lynnfield) over a maxed out quad core penryn? Only time will tell on that.
