Interesting layout of the cores. I was expecting all 6 in a row in the middle.

What we want is software to make the use of the cores we already have not even more cores.

probably for better yields
Dunninton is the final release of a Penryn based processor, although they have glued on a shared level 3 cache in addition to the standard caches which are only shared between two cores so the cores will not need to use the FSB
.Its also a Xeon so it wont just drop into any old motherboard its socket mPGA604.
Hot on its heals will be Nehelem, and of course Nehelem will have a whole new range of options, at least 3 different sockets, 1 for entry/mid range, 1 for enthusiasts and 1 for workstations/servers.

Six core is going to be hugely expensive when it enters the market (in Xeon form atm). I don't think it's going to compete anywhere near quad by which time Nehalem will be released.

Also, the reason it's six is because I don't think Intel can fit eight 45nm core's on an LGA711-"sized" die.
6 because the die space that could have taken 2 more cores, is stuffed with a shared L3 cache? .
Still doesnt matter, this is a mPGA604 socket XEON, and probably wont be released in an LGA771, or LGA775 format before Nehelem is released anyway.

Is mPGA604 related to the Quad-Socket Xeon boards? (Meaning that you'd get a total of 24 cores?!).
What we want is software to make the use of the cores we already have not even more cores.
There is software that happily will eat numerous cores at full load.
Just most people never have a reason for more than 2.
I use 2-3 programs regularly that will max out my 3.6GHz quad core.
Nehelem cores are designed to run two threads at once, using hyperthreading, but it should be considerably more refigned than the old P4 version of hyperthreading.
So on an 8 core nehelem, you'll be able to run 16 threads in parallel
Going from 8 cores on 45nm, to 16 cores on 32nm, no problem at all for intel either, AMD dont hold an advantage over intel on cores per sq.inch at any given process level.
There is room on the 45nm process for 8 cores, the reason dunnington is only 6 cores is because they used the space for the last pair of cores for a level 3 cache. But because they are still based on penryn cores the level 2 cache is huge as well taking up a lot of die space. I believe nehelem will revert to a single shared L2 cache, which will free up a ton of die space.
Isn't the cache there because they are using FSB and there isn't enough bandwidth for more cores.
