Clocks are oddly the same on both chips.
Didn't even think of that, but then I'd be back at 4 cores where I was at with my original 3770k

Safe to say it is most likely the chipset. In AIDA (not sure how accurate it is) The 4930k CPU Package is 15.93W and CPU IA Cores are 6.94w. Idle voltage is .976 at around 1.2 Ghz

Most of the Idle consumption has to do with Mainboard, GPU and PSU.
That makes sense. I have a X79 Sabertooth. At this point I'm not going to go out and buy another motherboard. I have a very low powered AMD card in there, single slot. That doesn't use much.

Nothing crazy, the virtual machine does put it to the test though due to the VPN I have running on there. Some client devices I have do transcode with plex at 1080p, so It's nice to have a quick buffer with that.

My guess is you're looking at the unusable software power consumption monitoring and are not using a power wall meter, the same meter for both tested systems.
I was going based off my Cyberpower PFC 1500 battery backup with the Cyberpower PowerPanel. If that is the case, I should have used a wall meter instead. I still don't understand why the battery backup showing 80w Idle on the 4930k system and 20w idle with the 3770k
If this is truly the case (of inaccuracy with the battery backup software), than you're right. I looked up multiple Asrock Z77E-ITX Power Consumption articles just now, and none of them show under 60w idle. Then again, they may have video cards in the test benches. I was running with no GPU with that setup.
