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 AMD Ryzen 7 1700 is the least powerful of three new Ryzen 7 CPUs. The 1700 model has base and turbo clocks of 3.0 and 3.7 GHz respectively. Both of its more expensive siblings, the 1700X and 1800X, have higher clocks but they also have TDPs of 95 watts whereas the 1700 is rated at just 65 watts. Comparing IPC between Ryzen and Kaby Lake shows that Kaby Lake leads by a maximum of 9% which is great news for workstation users as this allows the 1700 to beat Intel's 6850K in multi-core workloads at almost half the price. Although the 1700 has great IPC it's somewhat limited by its relatively low (by Kaby Lake standards) clock speed which holds it back a little in both gaming and desktop workloads. For multi-core workstation use, the Ryzen 7 1700 represents the best value for money we have ever seen. [Mar '17 CPUPro]

Processor Rankings (Price vs Performance) August 2017 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating which is geared towards gamers. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
