The Intel i7-4500U is a dual core, four thread 4th generation Haswell ultrabook processor. Its most impressive feature is a TDP of 15 Watts which typically yields over five hours of battery life. Despite the i7-4500Us relatively low effective speed of 66 (compared to the average of the leaders), the i7-4500U is perfectly adequate for handling the majority of day to day computing tasks, but it will struggle to deliver on CPU intensive tasks such as video editing and CAD. Gamers should obviously look elsewhere as despite the impressive desktop performance of the integrated HD 4400 graphics, 3D performance is far from adequate for modern games. If the battery life is a priority, then downgrading to the cheaper i5-4200U will deliver 15% more life but comparing the 4500U and 4200U shows that the 4500U is around 17% faster. [Nov '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]
