Product Description

Intel Core i7 Quad-core i7-950 3.06GHz Processor BX80601950 Intel Processors

From the Manufacturer

The Intel Core i7-950 processor combines the power of four 3.06 GHz computing cores into a single processor, guaranteeing enough processing power for the most demanding applications. With 8 MB of smart cache, the Core i7-950 processor ensures that you get maximum responsiveness from your system, even when several intensive programs run simultaneously. Compatible with motherboards based on the Intel X58 Express chipset, the Core i7-950 processor takes your computing and gaming experience to the next level.

Intel Core i7-950 Processor features:
  • Four 3.06 GHz cores for better multitasking and multithreaded performance.
  • 8 MB of smart cache.
  • Integrated memory controller delivers higher memory bandwidth.
  • Quick Path Interconnect provides fast data transfer between the processor and chipset.

With four cores in one processor, users will experience better multitasking and multithreaded performance.

The Intel Core i7-950 processor delivers unmatched performance for demanding tasks. View larger.
Powerful New Microarchitecture Eliminates Slowdown
The i7 family is Intel's flagship processor, and for good reason. With the i7 family, Intel engineers invented a revolutionary new style of microarchitecture. They replaced the front side bus -- a longtime staple of processor design -- with a new technology called QuickPath Interconnect (QPI). Using QPI, the Intel Core i7-950 processor achieves unprecedented levels of bandwidth, and can use its four computing cores to their maximum potential.

To put it simply, users will enjoy faster and more streamlined processing than ever before. Your computer will handle multiple projects and applications without the slowdown you'd experience with a lesser processor.

Extremely intensive programs like high-definition media editors will run more smoothly and responsively. And you'll be able to experience next-generation games without frame-rate hiccups and slowdowns.

New Technologies Boost Performance
The Intel Core i7-950 processor also makes use of several other cutting-edge technologies:

  • Turbo Boost Technology allows the processor to run up to 133 MHz faster when it's operating below power/thermal limits.
  • Hyper-threading Technology enables more efficient use of processor resources, making the most of highly threaded software like media players and next-generation games.
  • Smart Cache Memory increases available RAM resources, leading to less lag while multi-tasking.
Media Editing and Sharing Easier than Ever
Whether editing high-definition videos, touching up family photos, or splicing up music, the Intel Core i7-950 processor provides the processing power needed. The processor's four cores are optimized to keep up with the most advanced digital editing software. It also accelerates DVD encoding and compression, allowing you to easily share your HD home videos with everyone.

Unparalleled Gaming Performance
With the advent of next-generation games, PC gaming is more immersive than ever. The latest games take advantage of multi-threaded programming, allowing for more realistic graphics, physics, and artificial intelligence (AI). But you need more than just a good graphics card with high GPU output to fully experience all these effects. Underlying the visual realism and advanced AI scripts are thousands of high-speed calculations that your CPU must process.

Fortunately, the Intel Core i7-950 processor is specifically designed to handle these calculations. Using multi-thread architecture, it has the ability to process thousands of graphical characteristics at once, resulting in a smooth and lag-free experience. Intel worked closely with CryTek -- the developers of the advanced game engine behind such games as Crysis and Far Cry -- to guarantee that gamers have an immersive and lifelike experience.

The Intel Core i7-950 processor is backed by a three-year limited warranty.

Contrary to popular belief, CPU chip fabrication is really an imprecise art, and manufacturing perfection cannot be found in this industry. The same series of chips, in this case the i7 900 series, are all manufactured from the same wafer. Whether or not they get the extreme designation and specified number is based on testing done on each chip after the fabrication process is complete. However not every chip is tested for a specific range in the series (e.g. 975).

Like any company, Intel has manufacturing quotas, so a certain number of 975s have to be produced each month, but beyond that, they don't run the harder tests involved with the 975s. So in reality, you could technically get a 965 or a 975 in the 950 mix, assuming all quotas were met for any chips above 950 in that particular month of fabrication. The main reason for this is due to the limited demand on the 965s and 975s. In the end, it's more-or-less the luck of the draw.

Technically, this means you could by chance end up with a 920 that matches the quality of a 950 or higher. However, the chances are more likely that you could get a 975-quality from a 950 batch, since both would come from the same vicinity on the wafer (that vicinity being the area that consistently yields the best chips) whereas the 920s are coming from a known lesser-quality area of the wafer. The 920s typically are the bottom of the barrel in the series.

So if you're absolutely picky and you must have top-of-the-line equipment, definitely go with the 975 or one of the other extreme edition CPUs, because you're guaranteed to receive a chip of the highest quality (assuming you can afford it).

The best thing about the Core i7-950 besides its incredible benchmark performance and rock solid overclock ability, is that it's price tag keeps dropping, and with Sandybridge processors just about to enter the market, they'll only get cheaper from here on out. Boasting 4 cores and 4 threads, these are beast CPUs that have to be taken into consideration for any serious gaming rig or video rendering build. I bought this processor on a really nice deal at a local computer store--sorry Amazon but the price difference was too significant--and have been happily enjoying my new computer build for a while now.


In a word: easy. If you know something about overclocking older intel chips (dual and quad core 45nm and 65nm chips), you'll find that while some things have changed (bclock vs FSB) many others work about the same, and in particular managing Vcore, RAM timings, and micro-tweaking voltages to get the most out of your chip. There are many, many excellent resources on enthusiast boards that will guide you through the process--just employ Google to get the information you need. Most i7 chips OC about the same, so even a i7-920 guide will get you pointed in the right direction.

Suffice it to say I was able to achieve a solid 4.07ghz 24hr Prime95 stable system with temperatures never north of 78C. I idle at about 45C, and gaming pushes my temps into the high 50s or low 60s. I am extremely impressed with the quality of the overclock, and the relative ease with which I arrived there.


Stellar across the board. I have a gaming rig with a crossfire arrangement which I also use for video editing, photo editing, streaming media files throughout my house (using PlayOn and several WD TV Live devices).

I use Zbrush, 3DStudio Max, and Photoshop - all of which are very demanding on the processor. My old PC wasn't cutting it anymore (Core 2 Duo E6600) - especially when rendering normal maps from high-polygon models (it took so long to render). With this Core i7 950 in my new PC, the process of rendering was exponentially faster. What took me several minutes to render now took literally seconds. I've heard that this processor isn't the best in terms of oveclocking ability versus cost ratio, but since I never do that - I have no complaints.

Purchased this processor on 12/20/2010 for $199.99+tax in California for a total just over $217. Great bang for the buck. Super fast and can run everyone of your applications at the same time with no holding back. Pair with a SSD (solid state drive) and sit back and enjoy boot up speeds of under 30 seconds and the fastest processing this world has to offer at this time.
Would recommend to anyone!!!
