ThinkComputers posted a review on the Intel Core i7-4770K Haswell Processor
A quote from the article:
Just a year ago Intel launched their Ivy Bridge processors and now a year later we have another platform launch from Intel. The 4th Generation Core Haswell processors are the “tock†to Intel's tick and tock release schedule. A tock represents a new architecture and a tick represents a process refinement. So Haswell brings with it a new architecture, but is still built on the same 22nm process as Ivy Bridge. Intel has introduced a new LGA1150 socket with Haswell and a new chipset so you will not be able to throw this processor in an older motherboard, you will have to buy a new one. Today we are taking a look at the top of the line Haswell desktop chip the Core i7-4770K. Of course the K denotes that it is an unlocked processor. This is a quad-core processor that has a default clock speed of 3.5 GHz and a turbo frequency that goes all the way up to 3.9 GHz.Intel Core i7-4770K Haswell Processor Review @ ThinkComputers.org
