X99 is Intel's server chipset, is it not? And 2011-v3 socket boards are typically X99 chipset. X99 boards are more expensive than consumer socket boards from what I have seen and that only adds to the huge cost needed for the HEDT chips. If AMD has THEIR 8 core 16 thread CPU on the same socket and chipset as they hex and quad core CPUs then they have already beat Intel in value by making it so you don't need a more expensive chipset and/or socket to run their most powerful CPU.It is not. That is the CXXX chipsets:

As far as price differences... its really not that much at all when compared to 6700K/Z170. For example...
6700K = $350 (this price just recently dropped)
5820K = $389
Decent Z170 board $150-170
Decent X99 board $190-210 (these prices have went up. I did this exerciser 2+ months ago and there were $170+ boards... BW-E is releasing soon it seems...)
DDR4 quad channel vs DDR4 dual channel (2x8GB and 4x4GB DDR4 3000 MHz CL15-15-15-35)...$20
So, to that end... you are looking at $100 difference between a Skylake 4c/8t versus a Hawell-E 6c/8t.
So again, yes, there is a small premium to get that over Skylake.
Here are some performance numbers:

That is one, indeed.. there are multiple however.
EDIT - The X99 chipset handles 6, 8, and 10 core CPUs while Z170 handles 4 core on down.
You forget that people who NEED that kind of multi-threading capabilities can EASILY make the cost difference up with doing their work 31-66% faster. How quickly does a skilled hourly salary eliminate that cost in the long run??? You are forgetting that part of it. When time is money, your initial investment is certainly a consideration, but one needs to take into account its return over time in productivity efficiency versus the slower CPU.
