The Intel Core i5-750 is a mid-range quad core, four thread desktop processor which is part of the Nehalem series launched in Q3 2009. Considering the age of this processor, its effective speed of 67 is damn impressive. It has a base frequency of 2.66 GHz, which boosts to 3.2 GHz turbo when under load and can be significantly extended beyond by overclocking. Combined with a decent graphics card, the i5-750 should give a reasonable gaming experience even by today’s standards. There are of course faster modern alternatives such as the i5-4690K, but if you already have the 750 with an older graphics card it's likely that your GPU will need updating before the CPU. Comparing the 750 and 4690K shows that the 4690K has an effective speed of 109 which is 62% faster than the now five years old i5-750. [Nov '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]
