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]

AMD released the FX-9590 back in July 2013 but it's not until recently that these processors have started hitting the shelves and even now prices are still extremely high. This is the first mainstream 5GHz processor but clock speed isn't the key performance indicator it once was. Comparing the 9590 to the 8350 shows that the 9590 has 16% better overall performance which is almost exactly in line with its base clock increase from 4.0 to 4.7 GHz. Despite this performance boost the 9590 still lags Intel's most recent 4770K Haswell processor by 26% and that's despite the AMD's 27% higher base clock. In terms of relative performance the AMD's strong point is Integer processing where it has 8 processing units vs just four (one per core) in the 4770K. Overall, especially at current prices, the 9590 doesn't represent good value for money. [Jan '14 CPUPro]
