The Intel Celeron G1820 is a value orientated dual core processor. It has passable single and dual-core performance but its multi-core performance is extremely weak. The majority of desktop CPU tasks are single and dual core so weak multi-core performance isn't generally a problem. The G1820 is priced very well and consequently represents great value for money. Comparing the G1820 and Pentium G3420 shows that the G3420 offers nearly 20% more performance which, particularly in the single and dual core categories, makes for a far snappier and satisfying desktop experience. The G1820 is a great value option but paying just a little more for a G3420 will be well worth it for most users. [Mar '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]
