Powerful New Microarchitecture Eliminates Slowdown
The Intel Core i5-750 processor implements a radical new style of microarchitecture. Intel engineers replaced the front side bus -- a longtime staple of processor design -- with a new interconnect technology called Direct Media Interface (DMI). Using DMI, the i5-750 achieves superior 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 i5-750 processor also makes use of some 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.
  • Smart Cache Memory increases available RAM resources, leading to less lag while multi-tasking.
Unlike the Intel Core i7 processor line, the Intel Core i5-750 processor does not feature Hyper-threading capability, so it will perform slightly worse when dealing with multi-threaded programs. Still, the Core i5-750 processor compares favorably with Core i7 processors in nearly all other respects.

Media Editing and Gaming Faster than Ever
Whether editing high-definition videos, touching up family photos, or splicing up music, the Intel Core i5-750 processor will provide the processing power needed. The processor's four cores are optimized to keep up with the most advanced digital editing software.

Compared to the previous generation of Intel Core2 processors, the Intel Core i5-750 processor can process HD video almost twice as fast. It also accelerates DVD encoding and compression, allowing you to easily share your HD home videos with everyone.

The Intel Core i5-750 processor is also designed to handle the intense calculations and graphical rendering behind today's latest games. It has the ability to process thousands of graphical characteristics at once, resulting in a smooth and lag-free experience.

The Intel Core i5-750 processor is backed by a three-year limited warranty.

Incredible processor for the money. Absolutely the best bang for buck CPU on the market right now. I laughed when this thing opened Photoshop in a couple of seconds. It eats anything in its path and blitzes through games. As a test, I opened about 20 applications (including Photoshop with it's heavy memory requirements) and switched quickly between programs in order to try and trip the CPU up. While I did this, I was playing music from a playlist of several thousand songs, painting/editing an image in PS, and most importantly, running Windows XP in a virtual machine inside Windows 7. 1GB RAM was dedicated to XP, along with 64MB of graphics memory. Would you believe it, there was no lag. Awesome.

I'm using it with a Gigabyte GA-P55 UD3R board, 2 x 2GB Patriot Viper II 'Sector 5' 1600MHz RAM, and Samsung's (latest) Spinpoint F3 hard drive (model HD501HJ). OS is Windows 7 32-bit. The whole thing runs beautifully! Just a heads up -- Windows 7 32-bit will only use 3.5GB RAM. No use buying more than 4GB in a 32-bit environment, and you need to make sure you buy RAM that will run at 1.65V or less. Do your homework before buying.

Had this thing doing 4GHz on the stock cooler with just a minor bump in voltage, mainly just to see how well it overclocks and scales with voltage increases. No complaints at all. The cooler will definitely be replaced as soon as funds permit. The stock Intel cooler is abysmal. I would not recommend anything but a minor OC using it. The cooler to buy for this CPU is the Prolimatech Megahalems, which isn't cheap, but those looking for superior performance need look no further. The Megahalems is the best choice.

Dynamic overclocking using Turbo Mode is excellent. The stock multiplier for the 750 is 20x.

This processor is part of a ground up gaming build that I've done and upon completion this little baby rocks. It is very fast and will quickly prove itself as something incredibly difficult to bog down. I don't think that I have been able to push this processor to its limits yet and believe me I've tried. I wouldn't waste your money or time considering a faster 1156 processor unless you have *EVERY* possible bottleneck accounted for. Believe me you won't be dissapointed.

Ordered on the night of feb 4th, shipped on the night of feb 5th, delivered to Miami on the 9th with Amazon free Super Saver Shipping. I got it in Trinidad 2 days later. I ordered it the same time with other parts for the computer but they all shipped the day after. The i5 came alone with a weight of 1.20lbs.

I run Windows 7 64 bit and it never chokes with any apps or games and I have not overclocked it yet. If you want a serious gaming system do not spend more on the CPU than this, put the money towards a better graphics card or better SSD. The turbo boost works flawlessly to throttle the CPU instantaneously as necessary. Using the stock cooler I get around 40 degrees celcius when on the net or office apps and depending on how aggressively I set the fan speeds at most it reaches 60 degrees celcius during the day while gaming NFS Shift, Modern Warfare 2, World at War. The CPU never chokes on HD resolutions, AA 2x or 4x on for gaming. The bottle neck for me I think is the GPU and hard drive. Videos run smoothly, there are no freezes or crashes. If I decide to overclock then I will upgrade the stock cooler, the intel stock one is more than adequate for now. It's been a few weeks now with no problems and I am very happy with the build. The pc is not in an air conditioned room so with a/c air you can expect to get slightly lower temps. The temp in the room probably reaches around 30 degrees at peak.

This CPU is amazing value for money, I predict this PC will last me well into the future, and when games get even more intense I can go xfire and get a SSD.

Love this I5-750. It's fast and cool. It runs under 50C under load in turbo @3.2G. Overclocked to 3.8g with stock heatsink. Convert video and play HDTV with ease.

Need to be careful with the selection of DDR3. Initially paired with A-Data 2x2G and had random blue screens. Changed to Corsair XMS3 CMX4GX3M2A1600C9 and problem solved.

Stock heatsink is on the small side, but it did get the job done.

Let me just get this out of the way from the beginning. I'm a gamer and for me I'm always looking at upgrades that will improve my gaming performance the most. Never, ever have I seen such huge improvements in my gaming framerates as when I decided to get a new cpu, motherboard, and ram combo. I had purchased a Radeon 5970, which I have also reviewed on here if your interested in reading that, hoping that would be the biggest improvement to my gaming. It turns at that although it was good, it was being held WAY back due to my last-gen setup. I'll post the old and new ones now.

Old

Intel Core 2 Quad Q9400 @ 2.4ghz
4GB DDR2-800 memory
Radeon 5970

New

Intel Core i5 750 OC @ 4.0ghz
4GB DDR3-2000 memory
Radeon 5970

This processor is insane. Even at the stock cpu settings my framerates were better than with the Q9400. I then OC'd it to 4.0ghz using Corsair's H50 water cooler to keep it around 34c at idle. During normal gaming use my temps stay in the 36-46c range most of the time. I rarely see the temps exceed 52c max while gaming. Only during an Intel Burn Test running all four cores at 100% load did I see temps hit 68c. I even have all my fans on the lowest settings. I am using 1.34vcore and 1.23v vtt right now as well, which is probably higher than it needs to be. I could lower these temps even more by reducing the voltage, so I may try that later on.

My gaming framerates have doubled now just by upgrading from a Q9400 and DDR2-800 memory to this i5 750 and DDR3-2000 memory. This is such a great processor and one I highly recommend over anything else right now. Check out benchmarks all over the net and you will see that when this processor is OC'd to match the i7's, it can hang with those and even beat them out in some games for framerates.
