PCPER.com: 5 GHZ+ Phenom II Overclock on Dry Ice, 6Ghz on LN2

[Calmatory]

but why it took so long no one knows.

Their 45nm process is so much better than their 65nm process, and the huge core was a tad too big slice of the pizza for the 65nm, even Intel said that they wouldn't have done it on 65nm. Now the 45 nm seems to work fine.

So far nobody has talked about perfomance. Who cares if it can clock to 4GHz if perfomance is equivalent to a 400MHz less C2Q. I guess we won't have any proven info about that until we reach the launch day (that doesn't include Mark's blog and similar, just in case).

Take Agena results. Then multiply them by 1.05-1.1. There is your theoretical Deneb result with the 5-10 % IPC improvement over Agena. 3 GHz Agena scores 100 points in test X. How does 4 GHz Phenom II perform? 100 * 1.333 * (usually take something between 1.05 and 1.1). E.g. 100 * 1.3333 * 1.07 * 0.96(scaling factor) = 136.95. Thats 36.95 % faster than 3 GHz Agena. What about 2.6 GHz Agena? 100*0.86666*1.04(scaling factor, inefficiency from going from 2.6 to 3.) = 90.

However, that assumes that NB clock scales with the core clock which it does not AFAIK. But that should be roughly estimate.

You knew this already, I know it.
