Unlock your full potential with Intel's top-of-the-line desktop processor and experience total creative freedom that's limited only by your imagination.

  • newegg Hexa-Core Processing on 32nm Process, plus Unlocked Core Multiplier With six independent execution cores in one processor package, the multitasking monster Intel Core i7-990X Processor Extreme Edition delivers astounding multitasking and multi-threaded performance across many types of applications and workloads, taking your desktop PC experience into a completely new realm of mega power. Intel's breakthrough 32nm process technology incorporates 2nd generation of high-k + metal gate transistors for improved performance and energy efficiency. In addition, the processor’s unlocked core multiplier provides easy overclocking of the processor and memory frequency, enabling performance beyond the processor’s original specifications.
  • newegg Integrated DDR3 Memory Controller With the integrated DDR3 memory controller, the Intel Core i7-990X Processor Extreme Edition enables three channels of DDR3 1066 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. Plus the memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
  • newegg Intel Smart Cache Intel Smart Cache Technology dynamically allocates the shared cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from faster, more efficient cache subsystem resulting in significantly reduced latency for frequently used data and improved performance.
  • newegg Intel Turbo Boost Technology Intel Turbo Boost technology automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits, maximizing speed for demanding applications, dynamically accelerating performance to match your workload-more performance when you need it the most.
  • newegg Intel Hyper-Threading Technology (HT Technology) Intel Hyper-Threading Technology delivers thread-level parallelism on each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on the multi-threaded software of today and tomorrow.
  • newegg Intel Virtualization Technology (VT-x) Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.

had since came out, 2010, quality job 1.

Pros: still awesome in in 2019 ! like an old timex watch takes a lickin keeps on tickin ! all the super awesome new cpus still seem to suffer from premature death per many reviews Ive read and new motherbds. quality is poor.. I'll keep till she dies I guess. Ain't the fastest but overclocked, still very fast.

Cons: none

Reliable and Stable.

Pros: This processor runs wide open 24/7 in my InWin Ironclad case. It is rock solid. I do not use it for gaming. The system is also equipped with 3 video cards; 2 nVidea GTX 550Ti's and an AMD 7770. It does what I want it to do and has been for nearly 2 years.

Cons: The price is a bit exorbitant. Well, OK, it is extremely exorbitant. I feel I should have actually been able to build a Xeon machine for this price.

Great little CPU

Pros: Fantastic O.C potential, Kicks tail on everything I throw at it from 3D rendering, to heavy gamming. Currently sitting at 4.7 GhZ pared with Mushkin Black Line 8-8-8-24 Triple chan. Currently keeping cool with H100 close water loop, highest its gotten was 45c. Prime 95 88c. for about 8 hours. Sure its a little dated, but I think i can still woop some tail on most chips today.

Cons: There are no cons at this moment, nor i doubt there will be.

Who the heck would pay 1000 dollars?

Pros: None

Cons: Ridiculously overpriced. Why would anyone pay this much for a 6 core processor when you can find 8 cores for 1/5th of the price? Sure, this may be "insanely fast" as some of the poor fools have written, but its no faster than any of the other processors on the market. I feel sorry for all the tech-challenged folk who know NOTHING about computer hardware and shelled this much money for a processor.

Other Thoughts: How co

3960x

Pros: This processor leaves all others in the dust without even breaking a sweat. Even at standard clock speed this beast will dominate any task you lay before it. Ive been having trouble getting a stable 5GHZ CORE CLOCK but thats mostly because of my inexperience and cooling issues.

Cons: none

5/ 5

Pros: amazingly fast. best single proc setup i've ever owned. i use mine specifically for long running cpu-intensive tasks, and i just love how it tears right through stuff.

Cons: price, i suppose. if you're not a boss.

Nice!!!

Pros: It’s fast and easily overclocked. 12 cores really helps tear thru multi-threaded tasks. Like most i7 processors, it’ll take everything you can throw at it easily.

You can overclock it to the limit of your cooling system. I’m running 4 GHz on a water cooling system with max peak core temperatures of 74°C running 64 bit Prime95 in the stress test and loading all cores 100%. When I transcode video (88 megabyte/sec 30 fps, I frame only, HD 1920x1080), core temps stay below 67.9°C which is Intel’s recommended maximum temperature. The processor ran fine at 4.39 GHz but my cooling system wasn’t up to it.

Transcodes video faster than real time! Transcodes video faster thru the CPU than a GPU (and I have one of the faster, if not fastest video cards currently available).

Cons: Price! If it weren’t for the price, I’d rate it 5 stars.

Memory controller on my CPU was a bit twitchy. I overclock the memory bus to improve system performance. Didn’t overclock the memory as fast as my old processor.

Up to 12% slower than the new Ivy Bridge Extreme. You have to balance the cost of a new processor, cooling system, memory, and intended life of computer against the cost of the processor.

This may be the last 1366 processor Intel makes and its reached end of production!

Other Thoughts: If you want to breathe new life into an LGA 1366 system, get it! It comes with a huge heat sink/fan combo. People are reporting they use it for some impressive overclocks.

Awesome!

Pros: Another great processor from Intel. Worth every penny. You will love this chip! Windows 7 index gives it a 7.7 out of 7.9.
