You may wonder why the power consumption is so much higher than the Core i7-4770K's. Our investigation found that the engineering sample Devil's Canyon chip would auto-default to 1.152V in the BIOS, compared to 1.08V for the retail Core i7-4770K. A combination of higher frequencies and higher voltage increases system-wide power consumption by over 20 per cent. The chip needed all of this voltage, too, as it wasn't stable when we manually inputted 1.1V.
1.152 V is alright for 4.2 GHz 4-core boost. No idea how well it scales past 4.5 GHz though.

A word or two about temperatures: Intel says it is to use the same processor-in-box (PIB) cooler for this chip as for the 4770K. We used just such a heatsink during regular testing and found that, due to the extra power consumption generated by higher voltages, the Core i7-4790K ran hotter, at an average of 88C, compared to 78C for the older Haswell processor.

Hexus is normally great, but in a vain effort to be first out of the gate with a review, they are indeed going to be remembered as the worst reviewer, the whole point of this new K cpu is overclocking
and I wanted to see some proper results Shame....
This may explain why they didn't show any overclock results..... " it is reasonable to assume that overclocking plays a big part in considering this processor. However, our engineering sample exhibited unexpectedly poor overclocking potential, barely stable at an all-core 4.4GHz. We're awaiting retail samples before doling out advice on just how high the average Core i7-4790K is likely to go: stay tuned for that..."
So i just caught the live stream on the OCN Homepage. Right now ASRock has the highest 4c/8t clock speed of 5400mhz with DC. Come on ASRock haters? Let me hear it
Apparently their chip wasn't stable when they tried to overclock it, so I guess you can't blame them, really. Anandtech says their retail chip is coming later this week, with a review up later in the month.

Something isn't quite right about those results. I think they may have used an early ES, many of which had issues with high thermal load and power consumption.
There's are reasons why Intel delayed the availability and samples to reviewers and those two points are among them.
