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]
