QX9770 is 5 % Faster - Overlocking to 4 GHz
We simulated the Core 2 Extreme QX9770, as recommended by Intel, and can thus give you a preview of the processor’s performance once it actually makes its way into the market.
Compared to the QX9650 that was unveiled three weeks ago, the QX9770 is exactly 5% faster across our benchmark suite. The fastest 65 nm model trails the new CPU by almost 11%.
We can’t compare the performance to AMD’s equivalent offering, since the benchmark results of the Phenom are still unknown and this Intel CPU is still nothing more than a paper tiger that won’t be available in stores this year.
Overclocking the Core 2 Extreme QX9770 to 4 GHz can boost its performance by about 15 %, depending on the application.
FSB1333 vs. FSB1600
So what can the buyer expect from the front side bus speed increase from 333 MHz to 400 MHz? With the processor overclocked to 4 GHz using each of the FSB speeds, the faster FSB only showed a performance improvement of a meagre 0.5% - on average! The front side bus apparently has a negligible influence on performance, even at these high clock speeds. The performance delta measured here is so small that they may just as well be due to margin of error and fluctuating benchmark results.
The clear answer to our question is therefore, that the FSB speed increase does not translate into any kind of performance advantage for the end user.

hang on? pg 4, the table is in german (not that it matters, since the nm doesn't really change between language...
and on pg 7, that comment about it being for the enthusiast segment..... i'm not so sure...... since if its basically just a higher FSB version, most enthusiasts will just take it way higher anyway
I think it's hilarious how concerned intel were at the last article- it didn't put that bad a light on it as I remember...
lol intel got that CPU to you qwick and i am glad i did not by a x38m i would of bin pist D:
More upgrade confusion..great if you have wads of cash. Not so great for Intel as most people don't.
Best and most greatest selfish example of industry driven dribble I have ever seen. Pointless and further more petty baby steps towards getting the high stand. Nice.
Can't really see the point of this CPU.
Apart from neding a new chipset, what's the deal with a mere 5% performance increase for an additional 40% more power consumption.
Given the impressive energy efficiency of the QX9650, I don't understand how so much extra power is drawn for the tiny boost in performance - what's going on?
I think its important that you incorporate into your review on the qx9770 the following info I got from Intel support:
Thank you for contacting Intel(R) Customer Support.
The only cooling solution we recommend for this processor is the liquid based cooling. We can not guarantee performance nor reliability if an air cooling solution is used.
Please do not hesitate to contact us again if you need further assistance.
Sincerely,
Intel(R) Customer Support
