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.

Why look at the 9550? Even if you are running stock the 166mhz difference between it and the 9450 is hardly worth the extra $215 imo. I would also wager that if you are going to overclock, the overclocking results are likely to be neck and neck between these 2 chips. I would say the 9550 is for non-enthusiasts who just don't know any better.

I would go for the Q9450 and overclock it, chances are you can get far better performance out of it than even that $1599 CPU.

it has an unlocked multiplier, and is of a higher quality bin. basically it OCs better, and they are in short supply while demand is high... therefore it costs significantly more.

if your on any sort of budget go for the cheaper model. it will OC nearly as well. reports are showing 4ghz on air!

The Q9450 is the sweet spot. It is the same price as the E6600 when it was first released.

Expect to pay a premium during the initial first 6 weeks for the Penryn CPUs because demand will outstrip supply. I paid about $380 for my E6600 during even about 5 or 6 weeks after it's introduction.

so what is the difference between the qx9770 and the qx9650? they both have unlocked muptipliers! So would like the q9650 be 333 * x = 3.0ghz, while the qx9770 be 333 * x+1 = 3.2ghz(yes, my figures of 333 might not be accurate but u get the point.)And the qx9770 is $600 more?

binning, thats all. it just turned out to be higher quality during fab.

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.

its still Q1'08

Go for the Q9450. 1333*2=2666 (2.66). You don't use a half step multiplier that way. Also if overclocked 1600*2=3200(3.2) with no or minimal vcore voltage increase for that speed.

Word on delays past Q1: None. I'm still expecting Yorkies in two weeks, but I may be whistlng Dixie, so in that case I'll buy an E8500/8400 by the end of the month.
