The Intel G3258 is the first budget Pentium processor to feature an unlocked multiplier. This enables a comfortable overclock to 4.3 GHz using just the stock heat sink and fan. At 4.3 GHz, in terms of single and dual core performance, the G3258 challenges a fully overclocked i7-4790K, the fastest CPU I have seen to date! These results are stunning considering that the G3258 is retailing for around one fifth as much as an i7-4790K. The G3258's Achilles heel is its poor multi-core performance which is over 50% weaker than the group leaders. For the vast majority of users, assuming an overclock of 4.3 GHz, the G3258 is the best value processor on the market by miles. On the other hand, users that encode multi-media or run SLI/Crossfire setups should look elsewhere. [Jul '14 CPUPro]

The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]
