So, lets see. You don't believe that 4GHz 45nm C2D with 65W TDP is possible?
According to the 45nm High-K + metal gate parameters(Vcore, IdSat, etc) it provides 30% lower transistor power consumption at 20+% higher frequency.
Lets consider a 65W TDP E6700 as base in the calculation.
2.67GHz * 1.2 = 3.2GHz
65W * 0.7 = 45.5W
If for the 45nm @4GHz the Vcore remains same as for 3.2GHz, it will waste 56.875W.
(4GHz / 3.2GHz) * 45.5W = 1.25 * 45.5W = 56.875W
To 65W, there is +14.3% headroom.
65W / 56.875W = 1.143
Or you can increase Vcore to +6.9% and still be in 65W TDP.
Square root of 1.143 is 1.069.
All E6700 can OC at least 25% and be stable at default Vcore. So, its not a miracle for 65W TDP Woldfdale to have 25% higher clock at 7% higher Vcore.

a nice calculation of very very big fanboy, that's completely rubbish, if you're calculation is true they should already brought 65nm above 3ghz and they will never do that because of TDP increase and you are talking about 4GHZ . downplay every comment and reply in an AMD thread and try to keep the heads up in an INTEL thread.

as stated before, if you don't have any decent NDA You are just another one in line that needs info from the web. try to live with it.

Looks like old info. The busses have gone up since.

Also the product launch is in 2007.

indeed it will be end oktober-begin november you will see Penryn in retail

Not really, unless you use a highend SLI/CF setup. The appealing part would be quadcores. Personally I wait for nehalem. Since K10 looks like a R600 hype aswell.

yeah sure and Nehalem is not a hype? first onboard memory controller (the old 386 does not count, that's old tech) , csi, .... it is still early dev and paperwork and offcourse fanboy's like it already.

I dont think Nehalem is hyped yet. it sure will be closer to the launch.

What about 486SL then?

Onboard memory controller is only useful for the multisockets systems as I said before. For the desktop its 100% useless. Its just a sideeffect from the server oriented design. And in my eyes its a somewhat bad one. Just look on 939->AM2->AM3 situation.

But since Nehalem is a new architecture, I would expect alittle more and better than Penryn over Conroe. And I say I wait on nehalem because I dont believe in K10 hopes (It looks great for the bigger servers tho). Nor do I believe Penryn will make my Conroe obsolete before Nehalem.
