Wow...if this doesn't prove that cpuboss has jumped the shark, nothing else will!!!

The 4790k and 6700k scores must be reversed. Unless the intent was to score the older, slower, proc higher yet give the win to the newer, faster part regardless.

I like how in the end they go e you the bias opinion that the desktop processor is better even though the mobile scored higher over all. What is the target usage? If im buying a laptop with a 1060 and 16gb ddr4 2400 I'm not going to pay an extra 275$ for the k, when the hq with give me almost the same performance bit with greatly improved energy consumption. And why is over clocking even a factor. The amount you can over clock safely vs what the CPU already turbos to is less than 500mhz total. And again, it's a laptop. Soooooo unless you don't have a desktop it's completely pointless to go with the k model.
