that is a crazy shit rate you got there. i have a i7-6th gen 6700HQ @ 2.60ghz and my rate is only from 45 H/s ~ 50 H/s with 20 threads running. It nearly crash my laptop when i set to 30 threads. Why my processor is better than yours has a lower hash rate? LOL. Btw, my browser is crashed after i leave the mining on for like 3 hours.
You're comparing a desktop with a laptop, the processors are very different beasts. Laptop ones are designed for efficiency ahead of performance. My old i53570K @3.40GHz is giving me 60H/s. But power consumption is 67w idle to 121w peak. Your i7 maxes out 45w.
Regarding the power consumption, you can use a software like
HW Info to check how many Watts your CPU is using when idle and when mining and then do the calculations to see if mining is worth it for you.
Thanks for the link I'll check it out later.
