The Intel Core i7-4770 features Intel's most recent (Haswell) architecture. As with each of the previous "Core i" generations Intel have managed to reduce power consumption and simultaneously increase processing throughput. The i7-4770 has a locked multiplier which makes overclocking it much harder than its unlocked i7-4770K sibling. Comparing the 4770 and 4770K shows that the 4770K yields 14% higher processing throughput when overclocked and also costs 14% more. The 4770K has 4 physical cores which allow it to process four streams of instructions in parallel. General desktop computing tasks such as checking email, watching videos and surfing the web rarely require more than two cores, so for the majority of users this processor is overpowered. If you plan to encode video or compile software then this is one of the fastest reasonably priced processors available. [Mar '14 CPUPro]

MORE DETAILS

The Core i7-2700K is a 3.5GHz Sandy Bridge processor. Sporting four cores and eight threads the 2700K has a strong performance profile, even by today's standards. Comparing the 2700K and the 4770K shows that although the 4770K is two generations and nearly two years newer there is still only around 7% separating the processors in terms of overall calculation throughput. The 4770K does have a 12% lower TDP and it's also compatible with Intel's latest platform so as a new purchase it is the clear winner, but owners of the 2700K are only missing out on marginally better performance. [Mar '14 CPUPro]
