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 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]
