Intel Core i7-875K 2.93GHz Unlocked Quad-Core Processor Review
Legit Reviews posted a review on the Intel Core i7-875K 2.93GHz Unlocked Quad-Core Processor

In a move that shocked many, Intel has buckled to the demands of mainstream consumers and has launched a couple unlocked processors for the LGA 1156 platform! The processors that are being announced today are the unlocked Intel Core i7-875K and Core i5-655K processors. Read on as we take the Core i7-875K processor for a test drive and overclock it up to 4.5GHz with just air cooling!

The Intel Core i7-875K is priced $238 under the Core i7-870 that is exactly the same processor, but locked. This is an amazing price difference as the Core i7-875K costs a whopping 41% less than the Core i7-870. It's not every day you see Intel do something like this and if you are wanting a Lynnfield processor the Core i7-875K processor is the obvious choice. You get an unlocked processor for the LGA 1156 platform and the price can't be beat if you want the fastest processor that money can buy for this platform...

PC Stats takes a look at the Intel Core i7-875K and Core i5-655K Unlocked Processors

Intel's Extreme Edition processors are great for overclockers because of the unlocked aspect of the multipliers but not so great on their wallets. What if instead of $1000+ you could get a Lynnfield or Clarkdale CPU formuch less and still get the benefits an unlocked CPU offers tooverclocking? Well good news: Intel's new K-SKU parts are just that!

Hardware Canucks posted a review of the new Intel Core i5-655K & Core i7-875K Unlocked Processors

Enthusiasts and gamers alike are aware that AMD has long been catering to the overclockers among us with their unlocked yet affordable Black Edition processors. Meanwhile, Intel's unlocked products have largely been reserved for their ultra high-end Extreme Edition products but that is all about to change with the introduction of the K-series of i7 and i5 1156 processors. In this review we take these chips to their limits in order to see if their unlocked multipliers are beneficial to the end user.

Core i5 655K and Core i7 875K processor review
The Guru of 3D posted their Core i5 655K and Core i7 875K processor review

Intel today releases two new processors targeted at a somewhat more enthusiast audience. Yes, processors for tweakers and overclockers. On socket LGA 1156 Intel now releases two K series processors. The 32nm Intel Core i5-655K processor has the very same specifications as the Core i5 650; it will operate at 3.2 GHz, will feature two cores with Hyper-Threading technology, sport 4MB of L3 cache and will be made using 32nm process technology. The difference between the 650 and 655K is the unlocked multiplier only.

Then we have the enthusiast class Intel Core i7-875K processor, it has the very same specifications as the Core i7 870; it will operate at 2.93GHz, will feature four cores with Hyper-Threading technology, sport 8MB of L3 cache and will be made using 45nm process technology. The only difference between the two central processing units (CPUs) will be the unlocked multiplier on the 875K chip, which will allow overclockers and enthusiasts to easily boost clock-speed of the product without the necessity of overclocking other parts of their systems.

Intel's Core i5-655K & i7-875K Unlocked Processors
Techgage posted a look at Intel's latest "K" unlocked processors

For years, AMD has been offering Black Edition; processors that cater both to the consumer who wants the best AMD has to offer, and overclockers who want as much flexibility as possible. The reason is unlocked ratios and multipliers, something that on the Intel side required expensive Extreme Edition processors.

Given that Intel has been on top of the processor game for years now, it's difficult to say that the company has finally caught up in this regard, but it has. There's no fancy naming scheme here, though... simply a K at the end of the model number is all you need to look for, or alternatively, the word Unlocked on the box.

Intel K Spec Core i7 875 and Core i5 655 Review
OCC has published a review on the Intel K Spec Core i7 875 and Core i5 655

These processors are unlocked and meant to be overclocked. This is why both processors reached in excess of 4.5GHz for screen shots and between 4392MHz (i7 875) and 4461MHz (i5 655) for prime 95 stability. This however, took some work to get accomplished as both would easily get close to, or over the maximum clock speeds with just the use of the multiplier for overclocking. In order to really get as high as possible, multiplier and bclock tweaking was required.
