Keith, first you are wrong that Conroe will be restricted to a 65W
power envelope. That is for mainstream parts, but not high-end.

Thanks. That explains it partly.

As for Merom, that one is restricted to a much smaller power envelope than even mainstream Conroe, and is thus not relevant to
determine how high Conroe will clock at its debut (that is btw. supposed to be later than Merom). The fact that Turion is currently restricted to 2.2Ghz doesn´t exactly mean that DT A64 will not get to 3Ghz (or 2.8Ghz already today). Actually, if you add 600Mhz to Merom´s speed, you get to 2.93Ghz, and that is what I expect for Woodcrest. Conroe could be close or slightly higher clocked.

Conroe and Merom are based on the same design and hence Merom's debut frequency is relevant to get an idea for Conroe's frequency (I think you agree with this). I'm not sure if I can expect Merom mainstream to fit in the same power envelope as Yonah mainstream (31W). I am quite sure however that Conroe power headroom vs. Yonah mainstream can't be exclusively spend on frequency increases as Conroe includes the 64b functionality that Yonah is lacking. Ofcourse the designs are different but even more importantly for power consumption is that they share the same process (Merom/Conroe might have slightly more advanced power saving techniques but the logic part of the cores is likely to be somewhat significantly bigger than Yonah's). So in conclusion I still doubt if you can add 600MHz to Yonah or Merom clock speed to get Conroe mainstream version max clock frequency.

Also I heard that Woodcrest TDP would be between 70-85W. Do you know if that's correct?? If it is I expect Woodcrest to clock just as high as Conroe mainstream.
