From the Manufacturer

From the Manufacturer With multiple computing “brains” inside one processor, new Intel multi-core processors deliver big performance for anyone interested in running the most demanding software applications with ease. New Intel® Core™ i7 45nm quad-core processors from Intel combine exclusive innovations to deliver the best possible performance, plus an extra performance boost when needed.
Intel® QuickPath Interconnect (Intel® QPI) Extra burst of speed
Each of 4 cores effectively performing two threads of processing workload Multimedia
New levels of brilliant performance
With faster, intelligent multi-core technology that applies processing power where it is needed most, new Intel® Core™ i7 processors deliver incredible breakthroughs in PC performance. You’ll run multiple demanding applications faster and unleash incredible digital media creation possibilities. And you’ll experience maximum performance for everything you do, thanks to the combination of Intel® Turbo Boost Technology and Intel® Hyper-Threading Technology, which dynamically maximize performance to match your workload.

Puts processing power where you need it most
Whether you’re casually checking email and surfing the Web or running multiple compute-intensive applications like HD video encoding, you want a processor that can deliver maximum PC performance and keep things moving.

Faster, brilliant multi-core performance
With the Intel Core i7 processor, you’ll get performance that goes as fast as you do. An unprecedented 4-core, 8-thread design made possible by Intel® Hyper-Threading Technology ensures incredible performance, no matter what your computing needs. And with more than double the memory bandwidth for faster memory access, you’ll achieve more while waiting less.

Intel Technology Intel® QuickPath Interconnect. This Intel-exclusive innovation makes it easier for data to move quickly from the processor to the Intel X58 chipset, delivering better performance and responsiveness with the most demanding applications.

Intel® Hyper-Threading Technology. By allowing each of the four processing cores to process two application “threads” simultaneously, Intel Core i7 processors can accomplish more simultaneously—allowing users to run more demanding applications simultaneously while experiencing superior responsiveness.

Intel® Turbo Boost Technology. This new technology dynamically increases the processor’s frequency when needed by taking advantage of thermal and power headroom when operating below specified limits, giving you extra horsepower when you need it.

8 MB Shared Intel® Advanced Smart Cache. By placing more data closer to the processing cores and enabling multiple cores to dynamically share this space, Intel’s exclusive cache design ensures that multiple processing cores have ready access to data when it is needed.

Shatter your limits
It’s time for digital content creation that’s limited only by your imagination. Experience total creative freedom with the power to encode video up to 40% faster.1 Plus, enjoy incredible performance on other multimedia tasks like image rendering, photo retouching and editing.

Gaming on the edge—and beyond
The Intel® Core™ i7 processor not only can take on today’s most complex and immersive games, but it’s also powerful enough to handle tomorrow’s advanced gaming applications. By distributing AI, physics, and rendering across 8 software threads, the Intel Core i7 processor lets you concentrate on taking down the bad guys while your PC handles all the visual details like texturing and shading that keep you feeling totally immersed. It’s a gaming experience so perfect, you just might lose yourself in the action.

With professional-grade photo and HD video editing applications growing in popularity, you might have considered editing your own photos and home movies for family and friends. But did you know that these editing applications can consume huge amounts of computing resources? Built to handle resource-hungry creativity applications with ease, the four cores and eight processing threads of Intel Core i7 processors help ensure that when you’re manipulating high-resolution photos or editing HD-quality home movies, your computing platform will keep pace with your creativity.

Whether at work or home, running multiple applications is commonplace. When these applications demand significant computing resources (like photo editing, video compression or conversion, video conferencing, gaming and more) multitasking can mean slowdown and inefficiencies. For users who want to accomplish a lot simultaneously—whether at work or play—Intel Core i7 processors combine Intel’s latest exclusive technologies to deliver performance to match the task at hand.

The purpose of this review is to evaluate if the i7 940 is a worthwhile purchase vs the less expensive i7 920. I cannot see any reason to spend the additional money for the i7 940. While overclockers or benchmarkers will gravitate to the i7 965 for obvious reasons, for more mainstream users, the i7 940 seems to be in a no-man's-land of a very moderate performance increase for a hefty price difference.

Comparing the i7 920, I7 940 and i7 965 is fairly straight forward. They all have the same architecture and features. The main differences are their operating thresholds. The i7 920 clocks in at 2.66ghz, the i7 940 at 2.93ghz, and the i7 965 at 3.2ghz. The i7 965 also has a faster throughput (quick path) of 6.2GT/sec vs. 4.8GT/sec for the 920 and 940. Each has 4 cores, and 8 logical cores available to the system. While few programs take advantage of that many cores currently, with the release of Windows 7 and CPU/GPU load sharing, that will change and allow multi-core hyperthreading processors like the i7 series really come into their own.

This 940 seems to be the worst of the i7 options. Only 10% faster than the i7 920, it costs almost 50% more. The i7 965 has the added advantage of a faster through put (quick path) that for an enthusiast would justify the hefty price tag. For the average user, I can see no reason to purchase an i7 940 over an i7 920, considering a simple overclock will have the 920 operating at over 3ghz. a 10% performance increase for a 50% price difference is not justifiable.

It is a good CPU. Middle of the road, not the fastest or slowest. 1st generation. I happen to have a handful of these systems. Was missing a 940 for a corporate system of mine. From this seller I received a 950. Seems someone messed up here. I used it in another set up. Gee, wonder if I would order from them again.

I bought this chip in the spring of 2008. Since about 2 months later, I have ran it OC'd almost consistently at 3.6-3.7 Ghz. Last year, my PSU fried, and frying my board as well. I was worried about the chip, but when I put it in my new board, it still worked like a charm. Matter of fact, the last six months it's now OC'ed at 4.0 Ghz.

I've had this chip in and out of boards 5 or 6 times, accidentally got thermal paste on the bottom of the CPU, even seen the heat numbers get up into the 90c + a few times when I was just starting out. This chip has taken it all and keeps performing.

I almost knocked a star off because the chip won't die, so I can't justify upgrading.

As for the review concerning buying the 920 vs. the 940, I'm sorry, but it just doesn't make sense. There is a reason why the 920's are clocked lower. Every I7 chip is made from the same material at the same time. The way they choose to clock them, concerns how close to "perfect" each chip is as they divide them out. Thus, a 920 is closer to the variance limit than the 940. For normal processing, that's not a problem usually. But if anyone is buying this chip to overclock, go for the 940 (if you aren't jumping to the LGA 1155 socket but don't want to spend any more money). This chip simply won't die... dang it.

To all of you people who took the advice of ConsumerAdvocate (dakotad555) not to buy this chip. Yeah, you shouldn't have listened to him. This chip is still going strong for me 7 years later. I've had this chip overclocked at 4 gigs for a little over 6 years without one hiccup. If you can actually find one of these chips on the shelf, they still retail for over $500.00 while newer "faster" chips are selling for under $400.00. I now have a new EVGA 980 Ti SC+ and OMG!. No bottlenecks and FPS's straight off the charts. The i7 940 is keeping up and then some. Sometimes, the "experts" are wrong.

This is a very good CPU, and you can overclock it a bit. However, be sure and buy some silver thermal grease to get a good heat transfer to the fan that comes with it. I tried an outboard fan with it, but the quality was disappointing and it did not get good thermal contact, so the Intel fan cooled it better.
