Probably not, since it would cannibalize their LGA-2011 market.

They wouldn't be selling many more six core CPUs, just different ones.

Some might say it would ruin Gulftown sales... Probably, but keep in mind that the desktop version of GT is sold as hex-core when the die natively has eight cores.
Intel at this point could just release an oct-core version of Gulftown.

Anyway... I'm just dreaming it would seem.

why no one like intel GPU?
intel image quality stuck in... 2005?

ntel sandy bridge image quality is as good as 2005, in 2011: http://techreport.com/articles.x/21099/11

I did not know this.
That's really stupid.
haha thanks for the info man!

Wow! That link is pretty mind-blowing. Never really knew how bad intel's image quality was.

It is called cost recovery. Basically Intel stockpiled a lot of 2500K with defective iGPU. To keep the cost down, Intel disabled damaged iGPU and resell it as 2550K. AMD also did this on Phenom II X4.

I'm not 100% sure but I believe that they would not only have to set up a new design (with 6, 8 etc. cores) but also use some of the existing production capacity to make them which then slows down production of the standard runs. And they're having enough problems with production already. I'd love to hear the percentage of fails but from all the signs it's sounding pretty high. You know it's bad when you lower the clock speeds below your last gen. because you're having problems producing viable chips.

You may be interested to know that Intel created a separate Ivy Bridge quad core die with the smaller HD2500 IGP and only 6MB of L3 cache. It's similar to how there were two versions of the dual core die for Sandy Bridge. One was 149 mm2 with 4MB Cache and HD3000, and the other was 131 mm2 with 3MB Cache and HD2000. The full HD 4000 8MB L3 quad core Ivy die is 160 mm2, so I wouldn't be surprised if the other quad core die will be under 130 mm2. Unfortunately that die doesn't seem to being used for any of the unlocked Ivy CPUs, as those have HD4000 graphics.

Are Ivy's Clock's lower? I thought the mobile parts are clocked significantly higher. As for desktops and servers, the 3770K at least matches the 2700K, the 3570K has 100MHz on the 2500K, and the Xeon E3-1290 V2 is 3.7Ghz vs 3.6GHz for the E3-1290. I'm not defending the pathetic clock speed gains, but they don't seem to be lower than Sandy.

Every fab holds their yield numbers close to the chest. Off the top of my head I think it's around 10% now...but don't hold me to that number. I just remember thinking "wow that's embarrassing" but every fab has similar yields on the same node.

Last I heard a few weeks ago intel couldn't keep the voltages in the designed range because of 22nm fab problems which was causing too much heat on the chip (tri-gates use much less voltage than planar but have much more surface area and thus current [w=v*a]) so they were underclocking the first series to keep it under the targeted thermal threshold. I don't think they solved the problem and produced runs in just a week or two but I don't know. I would love to read a REAL review of someone who's gotten the chip actually in their hands but so far all I've heard on that is "I heard from this one guy" or "I read somewhere that" etc.

They do, it is called Ivy-e...
