Difference between Extreme and regular Quad-Core 45nm CPU

I am looking into purchasing a new computer system and started by researching/shopping for the Processor (CPU) – of course the 45nm Intel Quad Core CPU’s are what interest me at the moment but I was a little unsure of the price tag for the QX9650 (> $1,000) so I did was research to see what else we could expect from Intel in the first quarter on 2008 and saw the following chart posted by a lot of people:

QX9770 3,2GHz 1600MHz 2x 6MB 136W Q1 '08 $1599
QX9650 3,0GHz 1333MHz 2x 6MB 130W 12-11 $999
Q9550 2,83GHz 1333MHz 2x 6MB 95W Q1 '08 $530
Q9450 2,66GHz 1333MHz 2x 6MB 95W Q1 '08 $316
Q9300 2,5GHz 1333MHz 2x 3MB 95W Q1 '08 $266
(of course – someone please correct me if these numbers look wrong)

Immediately my eye caught on the Q9550 at almost half the price – but it also raised a couple of questions I did not have any answers for and was hoping someone could help fill in the gaps.

Specifically what is the major difference between the QX9xxx (extreme) and Q9xxx series? I see a major difference in power (130W vs 95W) for a small difference in CPU (3.0GHz vs 2.83GHz) so what does the EXTREME line carry that makes it so much more expensive – or alternatively what would I be loosing out if I only got the Q9550 instead of QX9650?

(sucks that I do not see any news about a Q9650 anytime soon – guess the best non-extreme version will be the Q9550 for now).

Of course – any other comments or information would be much appreciated, I’m hoping to see the Q9550 in the next couple of weeks – any feedback about my choice would also be helpful.
 
the extreme versions have unlocked mulitpliers aka they can overclock better

not worth the money unless u are loaded
 
you can change the multiplier on the extreme models, something that usually allows greater overclocks. If you have the money to blow, then go for it...otherwise lower level models will oc great as well.
 
Does anyone have a clue when Intel is supposed to release the Q9550 or Q9450 45nm Quad CPUs? I know there is a lot of talk about Q1 2008 and I even noticed some stores are already pre-selling it - has there been any word on an actual release date? Or any word on possible delays to Q2 or more? (I'm pretty much waiting for these to become available but won't if I find out it won't be available until something like June/July.
 
im waiting on the same thing, q9450.

initial release was jan 20 but rumors say its pushed back due to some p35 problems and/or lack of competition. hopefully ces may have something to say about it, though i still have my fingers crossed for jan 20

the rest of my parts, sans a vid card have been collecting dust for the last few weeks
 
The extreme editions actually have meaning in this round of CPU releases. Before their overclock limits were negligibly higher than their locked counterparts. But as we head to CPUs with higher stock FSBs and lower multipliers, that unlock begins to make a difference.

Needless to say, your Q9450 will not reach an OC even remotely close to the QXs. You'll probably settle ~3.6Ghz range while the QX's (as we've seen) have been hitting ~4.6Ghz.

But I still think the QX's are priced well beyond their worth.
 
Agreed. If you are looking for the best OC on a quad, you're better off with a G0 Q6600 than a Penryn / Yorkfield Q9450. Besides, if Nehelem is really due out by the end of 2008, Penryn will have half the shelf life of Conroe.

Mark.
 
However to get >4.0GHz OC, you would probably need to spend a lot more for the cooling too, that plus the original price of the extreme CPU is imo a much worse buy than buying a lower performing Phenom. Sure you could have the fastest CPU in the world but does it really mean that much? I can build at least three Q6600 systems with that kind of money.
