Top Intel Ivy Bridge-E Core Processors To Still Pack Six Cores
Intel's 2011-launched Core i7 "Sandy Bridge-E" HEDT platform is based on a 32 nm silicon that's common with Xeon E5 series processors. While the silicon physically packs eight CPU cores and 20 MB last-level cache (LLC, or L3 cache), client Core i7 processors are configured with only a maximum of six cores, and up to 15 MB L3 cache. According to a MyDrivers.com report, the maximum core count won't change with next-generation 22 nm Ivy Bridge-E Core i7 processors.
Ivy Bridge-E will be an upscale of Ivy Bridge. Similar to Sandy Bridge-E, the silicon will feature up to eight cores and 20 MB L3 cache. In its Core i7 avatar, however, the chip will be configured with no more than six cores, and no more than 15 MB L3 cache. The new chip will introduce IPC improvements, PCI-Express Gen 3.0 certified root complex (one which NVIDIA will approve of), higher CPU core clock speeds, and support for faster memory.
TDP could be the only reason Intel isn't willing to unlock cores 7 and 8 on client processors. Eight core, 20 MB LLC-laden Xeon E5 models based on today's 32 nm silicon, with 130W TDP, barely manage to scrape the 3.00 GHz mark. Given that, the prospects for Ivy Bridge-E client CPUs to run with all cores and LLC enabled, and yet deliver higher clock speeds than predecessors were always going to be low.
Intel Core i7 "Ivy Bridge-E" HEDT processors are compatible with existing socket LGA2011 motherboards (subject to BIOS update), and are slated for Q3-2013.

Also, you really don't know how to multi quote do you? Because you never do.
We'll as long that it does have a stock clocks of 4Ghz or higher then I'm up for it... 6 cores it is. :toast:
Anyway remember that Intel squeezed 10 cores on a 32nm CPU (LGA1567) so I think that it won't be hard to get 12+ cores on a mature 22nm node.
Hell I'm not asking for a 10/12 etc core CPU but you know at least an unlocked 8c should be in Ivy-E lineup :|
Well if IB-E and Haswell-E are build on the same 22nm process then I see no problem IB-E being a true 8core., Since Haswell-E is suppose to be a 10-12core cpu (again build on same 22nm).
I was seriously thinking about IB-E 8core, but when I saw Haswell LGA1150 spec. over at anadtech I kinda changed my mind, there is just to much new stuff in Haswell.
www.anandtech.com/show/6355/intels-haswell-architecture/5 (page* 5-11, esp. page 6-9*)
And Haswell-E is still to far away.. meh, Haswell-E 8core would be my perfect dream machine :D
130W 32nm 10 core, it is clocked at a decent frequency too (2,4GHz).
I don't think that adding 2 more cores would increase the TDP much above 130W, of course if you clock them @ 3,4GHz+ then yes I agree but they could well be selling them at 2GHz/2,5GHz stock.
Who wants to increase clocks then could very well use liquid cooling (like I do) my 3930K pulls probably three times more than its 130W TDP. (I have it @ 1.5v-1.6v)
One could argue that the selling volumes might be quite low, but then they could simply make less of them and price them at a suitable premium to compensate. I might have bought something like this myself.
Anyway the current 3960/3970X models are a joke, twice the premium over a 3930K which is basically the same CPU clocked slightly lower and with the unlocked multi doesn't even matter.
Don't even try to tell me that 3MB L3 cache makes a noticeable difference, cause it doesn't.
X edition should have been unlocked 8 cores from the beginning, then I would have bought an X instead of the K edition.
"It does" is referred about what? The cache?
