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 i5-4460 is a slightly upgraded version of Intel's 2013 Haswell i5-4440. Comparing the i5-4460 and i5-4440 shows that the only change is an increase in both base and turbo frequencies from 3.4 to 3.5 GHz. In terms of effective speed the 4460 is exactly on a par with the average of the top ten user rated CPUs, not a bad result for an i5. Thanks to its four cores the 4460 is can easily deal with the vast majority of desktop computing (email, web browsing, word processing etc.). In fact this model is probably overpowered for the majority of users. Most users wont require the multi-core capabilities that the 4460 offers and will do better to choose a lower powered and cheaper CPU. [Jun '14 CPUPro]
