The Intel Core i3-4160 is a dual-core four threaded 4th generation (Haswell) processor. It was released in Q3 2014 and scores a respectable 91 for effective speed. With its base frequency of 3.6 GHz, the 4160 is fast enough to run the vast majority of applications smoothly and it’s very reasonably priced for its performance which make it a sensible choice even when considering building a gaming PC. Although the integrated Intel HD Graphics 4400 are absolutely fine for general desktop use such as web browsing and word processing they may bottleneck a gaming machine. A 20% price premium would buy the slightly older i3-4350 which has a 33% larger (4MB) cache but its only about 1% faster (full comparison here). Overall the i3-4160 represents the best value for money I have seen outside Intel's Pentium and Celeron range of CPUs. [Nov '14 CPUPro]

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]
