The i7-4900MQ is a top end 2013 Haswell Laptop CPU. It sports Intel's standard i7 configuration of four physical cores with support for eight hyper-threads. Comparing the 4990MQ and the flagship desktop i7-4770 shows that the performance gap between Desktop and Laptop CPUs no longer exists amongst top end Haswell based CPUs. Looking at the 4900MQ and the 3630QM Ivy Bridge Laptop CPU shows that the 4900MQ is around 30% faster, which is a big jump considering the relatively narrow age gap between the two. Overall the 4900MQ is a superb Laptop CPU that is able to give even the latest top of the range Desktop CPUs a run for their money. [Mar '14 CPUPro]

MORE DETAILS

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]
