Intel Core 2 Extreme QX9770 Previews

@ 2007/11/19

Since the launching of Core architecture in July 2006, INTEL declined the latter on all its ranges of CPU choking gradually AMD whose K8 architecture with end of breath cannot compete. This last will try however to leave the head water with the advertisement of Phenom and of its new news K10 structures. INTEL does not seem for as much not eager to slacken its pressure bus only 3 weeks after the advertisement of Core2 QX9650 (integrating 2 chips dual core 45nm) and the very same day the advertisement of Phenom, INTEL leaves its hat a QX9770 even faster. What to waste the day of AMD and to affirm still a little more like only maitre performances?

Built in memory controller would be Nehalem, not due till 3Q or 4Q'08ish.

Any other QX9770 chips displaying an unusually large power consumption? I've seen identical processors with completely different power consumption figures, all depends on chance until Intel has had 6 months to improve yields. 45nm is still new to Intel chips.

... and power usuage

9770 samples have been along almost as long as the 9650 samples. Other than that I tend to agree with you : it should be the equal of the 9650, but it clearly is not.

Another possible explanation could be the fact that it has to operate on overclocked chipsets, probably with VTT and northbridge voltages upped by quite a lot. This also has some effects on cpu temperatures.

early silicon? please explain, afaik 45nm is both on 9650 and 9770

The Ace card Intel holds forever; unlock mid-range CPUs.

, since
AMD is doing this all along.

I wish my PC skill will match P4 Northwood one of these days, or I could game halfway decent. Until then, I am quite content with what I have.

Does not look good.

Comment from jmke @ 2007/11/19

High powers consumption 192 vs 267Watt (9650 vs 9770) most likely due to massive power leakage, Prescott style. If you put better cooling on there, you will see power usage go down a notch or two
