With the Yorkfield core, Intel takes the Core 2 specification to the Extreme. This 45nm based processor is designed for lightning fast performance . It's fully 64-bit capable with the Intel 64 architecture so you can take advantage of the additional power and efficiency you'd expect.

L2 cache has been bumped to 12MB and the Front Side Bus to 1333MHz. You can use both DDR2 and the hot new DDR3 memory for extreme performance. They also boosted memory access and execution speed with the Wide Dynamic Execution and Smart Memory Access. These combine to let the processor compute more instructions with more data per clock cycle. You'd better watch out those in game enemies will be shooting back faster now.

The Advanced Digital Media Boost feature has been enhanced with the addition of the SSE4 instruction set and Intel HD Boost. This will give your entertainment experience a boost with better audio and video processing. It will also help with speech recognition, engineering and scientific applications. Perhaps most important of all will be the boost to security with increased encryption power and speed.

  • newegg Intel Core 2 Extreme Quad-core Processor With four processing cores, the multitasking monster Quad-Core Intel Core 2 Extreme processor delivers twice the performance on highly-threaded applications, taking your desktop PC experience into a completely new realm of mega power. The powerful processor delivers serious performance on the ultra-demanding games of today and tomorrow. The innovative 45nm quad-core technology optimizes thermal performance for reduced power consumption and noise.
  • newegg Intel Advanced Smart Cache Intel Advanced Smart Cache Technology dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from fast L2 cache, resulting in significantly reduced latency for frequently used data and improved performance.
  • newegg Intel Extended Memory 64 Technology (Intel EM64T) Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the desktop processor platform to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
  • newegg Enhanced Intel SpeedStep Technology (EIST) EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.
  • newegg Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
  • newegg Intel Virtualization Technology (Intel VT) With Intel VT, one hardware platform functions as multiple "virtual" platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.

5 out of 5 eggsNearly 6 years later and still running

Pros: Still running beautifully after 6 years of ownership, has yet to show any signs of age, it has unlocked multiplier so it is much easier to over-clock than normal Intel Core 2 processors. Runs almost as fast, sometimes just as fast as the Nehalem Intel Core i7's in most games. Have it running at 3.7GHz right now.

Cons: Needs a lot more voltage to reach a certain clock speed compared to the newer revision although non-multiplier unlocked, Q9650. Also like most Core 2 Quad processors, it runs very hot in comparison to the Core 2 Duos

Other Thoughts: Well worth the asking price, you'll need a much more decent cooler than just the off the market $20 cooler however if you want to do any serious over-clocking, which is technically what the Extreme moniker is designated for.

5 out of 5 eggsStill chugging away after all this time.

Pros: I've been running this CPU in my DFI Lan Party X48 T3-RS motherboard at 3.83GHz (water cooled) for nearly five years now. It won't die. It's faster than the "new" Xeon workstation I have at work. The most satisfying purchase I've made in a CPU.

Cons: I'll admit, it's getting a bit long in tooth. Time to upgrade! :)

Other Thoughts: Bought mine in November of 2008 just before the next generation of Intel CPUs were to be released. I walked into a local bog-box store retailer one day and saw a hand-written sign advertising the QX9650 for 50% off retail price. I couldn't pass it up!

5 out of 5 eggsWorking since 07 March 2008-20,554 hours of operation

Pros: My CPU has completed exactly 20,554 hours of operation as of today (May 15,2013). I only overclocked it in 2012. It works at 3.92 GHz, Loadline Calibration off, at a BIOS voltage of 1.455V and a load voltage of 1.37-1.38V. This CPU is very capable, I am playing WoW and SWTOR at max settings 1920X1080 ULTRA with excellent performance (GTX 580 & Asus P5Q Deluxe).

Cons: It wasn't free.

Other Thoughts: Originally cost me 797 Euro. I'd say it was well worth the money. We 'll see how long it will last. Planning to relegate this rig to a Folding@Home dedicated rig after I upgrade to Haswell later this year.

5 out of 5 eggsYou mean I never wrote a review?!!!

Pros: It is still working at the high end of PC greatness after more than 4years and 11 months of computer life.

Cons: none at all.

Other Thoughts: sorry only that I never rated it before now. it is a wow chip and I may never have to retire the pc it brings to life.

4 out of 5 eggs

Pros: It has performed well and I have had no issues. The blue neon fan looks great inside Silverstone Nvidia edition case.

Cons: This is my 1st build and I had some issues with the plastic connections of fan to motherboard. It seemed like a cheap way to connect fan for a cpu that was over a $1000. This was my 1st so maybe they are all made that way now.

5 out of 5 eggswas / is expensive, but awesome

Pros: Just FYI that these babies are capable compared to lesser 775 skt cpu's :
ASxS P5-ke, mushkn 1150 2x1 Gig @ 1100, cas4. CPU@4 Ghz @ 1.29v w/ Thermalrt Extrm, lapped Htsink w / 2 med spd and sound 120 mm fans ( one in, one out ).
30 deg amb temp, ~ 45-47deg, 4 cores loaded.
Load testing by simultan. running 50% vid recode and running " systester ", multithreaded pi tester w / no errors.

Cons: paid too much of course a yr ago.

Other Thoughts: only ran at 3.8Ghz for most of that yr, and said to heck w / it ( carefully ), and low and behold does 4.0 just fine.
ovrclk'd i7 may be still faster, but sck775 quad at 4 Ghz, who needs it...

1 out of 5 eggsWasted money

Pros: it's 3.0 ghz out of the box...

Cons: Where to start. It costs over a thousand dollars. Runs media terrible compared to my AMD 9600. It just feels jumpy. I have been thru all of the motions and I know that all of my problems lie in this processer. I returned the first only to get the exact same problems.

Other Thoughts: AMD is way better bang for your buck. Maybe this processer will overclock a little further but so what? The new Deneb is 3.0 and hit the market at 275$. This thing is a big waste of money. I was giving Intel another shot since they seemed to be ahead. They are only ahead on customer rip offs.

5 out of 5 eggsFast Chip!

Pros: --Great Chip! Bought it originally for FSX, works awesome!
--VERY overclock-able even with stock cooling!! @ 3.6Ghz
--Stock fan and heat-sink is respectable.

Cons: None really that I can think of.

Other Thoughts: This is not a con which is why I put it in the "Other Thoughts" section of the review, but the price has BARELY come down in over 10 months, I paid $1,060 for mine last February.
