The Intel Core i5-4690K is the latest incremental upgrade to Intel's unlocked mid-range quad core family of processors. The 4690K replaces the 4670K. Comparing the 4690K and 4670K shows that little has changed. The two chips share identical architecture; in fact the only difference between them is a 100 MHz bump to both the base and turbo clocks. The 100 MHz bump translates to an insignificant 2.9% performance increase. In terms of outright performance the 4690K has an effective speed of 103 which thanks to its superb single and dual core performance, is 12% stronger than the average of the group leaders. Overall the 4690K brings nothing new to the table so owners of previous flagship i5's will gain little by upgrading but as a new purchase the 4690K is a strong contender for both power users and high end gamers. [Jul '14 CPUPro]

MORE DETAILS

The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]
