The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

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]
