The Core2 Quad Q6600 is over 7 years old which is a lot of processor lifetimes! This particular model has been included in the group test simply as a reference because of its exceptional popularity back when it was at the forefront of technological advance. The Q6600's four physical cores demonstrate exceptional overclocking capacity and often achieve in excess of 40% performance increases. Modern Quad core processors offer nearly three times more performance on both single and multi-core workloads. There have also been lots of non-processing related improvements in the platform over the last 7 years which include SATA 600 MB/s, USB 3.0 PCIe and more. [Mar '14 CPUPro]

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]
