Intel Core 2 Extreme QX9650 - Penryn Ticks Ahead

Overclock Me Baby
Naturally we wanted to see how much was left on the table with Intel's 45nm process. We can't help but think that had Phenom been out sooner, we'd be seeing a > 3GHz Penryn launch, but how easy would it be for Intel to ramp up clock speeds?
Our unlocked QX9650 had no problems hitting 333MHz x 12.0, for a final clock speed of 4.0GHz. We had to increase the stock voltage of 1.25V up to 1.40V to achieve it, but the overclock required no additional cooling beyond the standard Intel heatsink/fan. At lower voltages, 3.66GHz should be an easy target to reach.

I'd like to point out that someone must have been tired when writing this. The graphs here on page 4 say "QX6950" VS "QX6850", simple reversal of the numbers, but I'd like to correct it for those that might be confused, took me a moment to figure out which was which myself the "QX6950" is ment to be the "QX9650", and obviously the "QX6850" is the correct naming.GL HF.

ew.intel again ftw. blech. They made a great chip. power usage is fantastic. One could get even lower total wattages (by far) if they concentrated on doing so. a quad core that can be cooled near silently. neat :)

Just a question, what was the difference from Core to Core 2? All I could ever fine was cache size was increased.Now that I'm thinking about it, why not the name Quadro? Oh, nVidia ownz it.

Core Duo (Yonah) was based on Pentium M.Core2 (Conroe) is a new architecture.

actually i found a comparison page about it, and core 2 isn't that much different from core. Yes, it updated a lot and gave improved performance. No, it is not a completely new architecture from PM, but you can say a big difference from the P4.http://www.anandtech.com/showdoc.aspx?i=2808&p...">http://www.anandtech.com/showdoc.aspx?i=2808&p...

On page 9 I believe you are grabbing some old benchmarks, old in the sense of your previous articles. I believe I pointed this out to you as a mistake, and now it is here in the bar graph. Again, how is it that the 2.33ghz C2D outperforms the 3ghz one?
