The relevant parts of the review

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.
Too bad they didn't stick a real heatsink on it so we can see how well the new TIM works.

Power:



TDP? What TDP?

They probably just wanted to be the first ones to release a review.

No temperatures to see if there's any improvement there with the new TIM. That's what i'm disappointed at most....

10C higher temps. However running ~1.2v+ on the stock cooler and only reaching 90C-ish is pretty good. Much better than normal 4770Ks afaik.

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....

He is also pushing a ES chip, [which is said to be a bad one at that],don't know if that is good or bad...regardless, I am all in..

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..."

5496 mhz to be exact...

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.

ASRock is still tops with 5998mhz with LN2.

Asus is the current air/h20 cooled leader at 5414

Never had a Haswell, is that good or bad?
