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 5930K is Intel's new middle tier Haswell-E prosumer CPU. This model has base/turbo clocks of 3.5/3.7 GHz and sports 6 physical cores with 12 hyperthreads. The 5930K offers enormous processing throughput but like its Haswell-E siblings it lacks in single and dual-core speed. Comparing the 5930K and 4790K shows that the 4790K offers nearly 20% more single and dual core throughput and is priced nearly 40% lower than the 5930K. The 5930K does win hands down on multi-core workloads but these are not generally relevant to consumers. Finally since the Haswell-E architecture is coupled with the X99 chipset it requires far more expensive DDR4 RAM with offers little upside over DDR3. ^{[Sep '14 CPUPro]}
