This is one of Intel's highest-value quad-core chips. It has very low power usage, a number of enterprise features missing on the 3770K, and does in fact overclock.

FEATURES:

i7 3770: 3.4 GHz
* Hyperthreading (4 actual cores, 8 visible ones)
* Partially unlocked turbo multiplier
* vPro, VT-d, Trusted Execution (for better security and faster virtual machines)

i7 3770K: 3.5 GHz
* Hyperthreading (4 actual cores, 8 visible ones)
* Unlocked base and turbo multipliers

The i5 3750 and 3750K have the same differences, but both operate at 3.4 GHz and neither has Hyperthreading. The latter can add 10-20% performance with heavily multi-threaded workloads like CAD rendering and video compression. VT-d reduces processor load with certain virtualized I/O operations by a factor of 2. For a workstation or server, I'd choose a chip with that feature, but verify that your motherboard supports it. Most ASRock and Gigabyte boards do; Asus boards for this chip do not. See the comments attached to this review for some useful guidance.

OVERCLOCKING:

The basic mechanism to determine clock speed is to multiply the system clock (a 'base' clock, typically 100 MHz or so that regulates the various other components in the system) by a multiplier. With modern chips, the multiplier varies dynamically based on system load. At idle, this chip operates at 1.6 GHz. At full load, it upclocks all four cores to 3.4 GHz. If the chip senses additional leeway in temperature and power use, the cores continue to 3.7 GHz. A three-core load could reach 3.8 Ghz, and two cores or less, 3.9 GHz.

Each core has its own multiplier that is often, but not always, the same as the others.

I believe this is an excellent CPU. It runs with no problem. I have a couple of additional comments to make, especially concerning some comments in other reviews. By the way, I used this to replace an i7-920 (which also required a new motherboard because it uses a different socket).

1. Although this CPU is supposedly not able to be overclocked (except for turbo mode), I find that is easily overclocked. My Asus P8Z11-V Deluxe motherboard (and its utilities) will automatically overclock it to about 4.22 G. It runs there 24 hours a day with no problems or instability. Of course, it won't overclock as much as the i7-1770K.

2. Concerning using the Intel CPU cooler that came with it: I used that at the beginning because I needed to get a different backplate for my CoolerMaster V8 CPU cooler. It did work, but was hot. With the V8 installed it runs more than 15 C cooler (at full load,(running folding at home with SMP (using 6 or 8 cores) and 2 GPUs) than with the original Intel cooler. So, if you overclock it and run it hard, I would recommend getting an after-market CPU cooler even though it will run somewhat OK with the original Intel cooler.

I highly recommend this processor.

I recently purchased a new Nvidia GTX 670 GPU to replace my aging GTX 470 and was not even considering a processor upgrade. However, even though my very expensive (in 1997) Intel QX6850 processor was still kicking bit, the old motherboard did not support the new and improved PCIe 3.0 that the new vid card was made to take advantage of. With this in mind, I decided it was time for a full upgrade and boy am I happy with the results.

In 1997 I paid 1100 dollars US for my quad extreme processor. Back then a quad core with 8 megs of internal cash running at 3 ghz per core was insanely powerful. This new processor not only runs at 3.4 ghz per core and has an identicle 8 mhz internal cache, but also has hyperthreading and uses significantly less power and produces less heat. All for just over 300 dollars US... a great chip. These features combined with PCIe 3.0 and DDR 3 as opposed to DDR 2 on the old motherboard has definately made the upgrade worthwile.

I went with the i7 3770 instead of the i7 3770k for several reasons. One, I never bother with overclocking as I think that is silly, if a given processor isnt good enough for me I will simply replace it with something faster. And 2, the i7 3770 actually is rated at a lower wattage rating and I like haveing its full suite of added security features that are missing on the i7 3770k. Lastly, it cost less than the i7 3770k with an extremely miniscule performance difference (again it still has all the security features that the 3770k is missing, a good trade off in my book).

Hope this helps.

Extremely happy with the speed, temp, and power draw of this processor. Seems to match the benchmarks of the 3770k (when that one isn't overclocked...). I even liked the stock CPU fan enough to use it instead of a aftermarket cooler (a first for me).

The installation of this processor and an Asus P8Z77-V Pro resulted in a fantastic change in what I value most - low power consumption! And that while markedly increasing system performance.

My previously installed system, an I7 950 on an Asus P6X68-E motherboard was dissipating between 117 and 163W while the newly installed one dissipates from 53 to 65W.

The old system was quiet, you could barely hear it, this one is virtually silent.

Overall an answer to my prayers!
