If you're after low-power computing then this is a good, basic processor to get work done. Based on the 2016 14nm Apollo Lake architecture it is designed for mobile efficiency and comes in a range of laptops from budget to mid-tier. It uses about 4 to 6 watts under load (yes, four to six whole watts) and generally idles under 2 watts. It has four cores with four threads and has a 1.1GHz base clock with a 2.2GHz boost, with the included HD 500 series graphics boasting 12 execution units running at up to 700MHz, although information regarding this is limited given its budget application. If you're processing data then forget anything with this. Although possible, it'll take forever as you're limited to 256k of L1 and 2MB of L2 cache - no L3 at all. The included graphics won't help you here either. For everyday processing, or a cheap laptop for the kids, this is a decent processor but throw more than 2 or 3 basic tasks at it and it flounders. Anything more complex than everyday word processing, internet and multimedia is beyond it, but given that's what the majority of users will be doing this isn't an issue. The bonus? Ultra-light, thin and quiet latops with passive cooling and sub- $250USD price points. Not bad! [Jul '19 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]
