The new ‘Skylake’ i7-6700K is introduced as a direct replacement of the i7-4790K price-wise and costs less than the ‘Broadwell’ i7-5775C.  The high price of the i7-5775C is quite obvious sitting very close to the i7-5820K HEDT part price-wise. Even without architectural knowledge of Skylake, the lower price tips that there is no eDRAM on the i7-6700K nor does it have the same impressive integrated graphics capabilities.

  1. DDR3L refers to a set of specifications, most notably voltage, for DDR3 DIMMs including, but not limited to, SODIMMs. It’s not just for laptops, and it’s not just the small sticks.

Got something to say, then say it!
