Small, low power chip with four threads designed for everyday computing like word processing and web browsing. Limited in design by its slow front side bus speed of 667MHz single-channel RAM with a max capacity of 2GB, it will work best with lightweight systems like Ubuntu / Linux and Windows 7. Despite its age and low power design those two hyperthreaded cores are more than capable of seamless tasking, just don't try too much at once. Youtube in 480p is just fine, and given the tiny 10" screen most of these CPU's are bundled in you won't need much more than that anyway. Gaming? Not much is going to happen here, given the integrated GMA 3150 chip. Updates for these things stopped long ago so unless you want to get funky with some hacked drivers you won't get much action there. Still, older titles from the late 90's should be playable with low resolutions and settings. Think Halflife, Max Payne, Age of Empires, Starcraft and Diablo 2 and you'll have realistic expectations. Overall, a good (if limited) budget CPU for basic everyday use. [May '20 boingk]

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]
