The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 CPUPro]

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]
