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]

MORE DETAILS

The Intel Core i5-4670K is the latest middle tier desktop processor from the fourth generation of Intel's Core range codenamed "Haswell". In terms of raw performance this processor slightly bests its predecessor the 3570K achieving approximately 10% higher server benchmark scores. In terms of real world performance the single core improvements are more relevant as more than two cores are rarely used for most typical consumer tasks and these have also improved by around 10% over the 3570K. It's not all good news though as the price increase of 14% more than offsets the performance improvements. This processor currently represents approximately the same value for money as its predecessor, the i5-3570K. [Jun '13 CPUPro]
