Intel unveils Devil’s Canyon, its first 4GHz CPU, plus a 20th-anniversary Pentium processor
Intel’s fifth-generation Core processor family—code-named Broadwell—might be late, but the company has cooked up a couple of brand-new Haswell-class desktop CPUs that PC enthusiasts are sure to dig. Code-named Devil’s Canyon, Intel unveiled the all-new Core i7-4790K and Core i5-4690K processors at Computex on Tuesday (Taiwan time). Intel is also marking the 20th anniversary of its Pentium processor by introducing the all-new Pentium G3258.
The Core i7-4790K is notable for its ability to run all four of its cores at a base clock frequency of 4.0GHz. Other Intel CPUs have been able to reach this frequency on one or several cores for brief periods (a burst mode Intel identifies as “Turbo Frequency”), but this new part will run that fast consistently and boast a turbo frequency up to 4.4GHz.

Thanks Bill, now I have the upgrade wants

I've just been reading up on the 4790 after getting the itch to upgrade my 4670k, and from what I can see the gains I'd get are negligible. Great chips for new builds or upgrades from older architecture, but from a Haswell (even Ivy Bridge) point of view it's probably just not worth it.

Not worth it or worth it...looks no choice now on Ivy's point of view: Seventeen Intel Ivy Bridge CPUs Are Getting Scrapped!

I think this is a clue. Keep it cooler and clock it.
The new thermal solution Graff spoke of is known by its very long acronym: NGPTIM (Next-Generation Polymer Thermal Interface Material). It’s essentially grease that the factory applies to the heat spreader housing the processo
No more de-capping needed for those that did such a thing.

From what reviews I have seen on the engineering samples, the 4790k runs 6c cooler than the 4770k, but the 4790k may require more volts which may negate that.
Delidding has been giving 4770k owners around a 20c drop.
I think the jury is still out on this.

Delidding seems have to be done in a proper way and put IHS back to gain temps looks not that easier, in particular with Air Cooler when its time to tight it on the CPU.
Hell is electrical tape, roller paper, nail polish, tricks with spacers...wrecked CPU! I can see myself Hammer & Vice!! But i can also see myself in a near future with Haswell i5 or i7 refresh!

Doesn't seem that hard to delid. The problem with the original haswell was not only the TIM, but the gap between the die and IHS was too large. Delidders cleaned off the IHS glue for a smaller gap and got much better results.
Just saying, from news so far, there may still be as much delidding on DC as original Haswell by enthusiasts.

At Computex 2014 there was a 4790K OC Challenge sponsored by Intel.
Several teams competed live on stage for cash prizes.
Intel provided the CPUs but it's unclear whether these were engineering samples or from a production run.
Stable 4 core 8 thread clocks ranged from 5.2 GHz to 5.5 GHz with closed-loop water cooling (custom loops weren't allowed). The top OC using LN2 was 6.3 GHz.
It remains to be seen if the CPUs that the average consumer gets will be able to OC to these levels. I'm definitely interested and I'll be watching the reviews in the weeks following the general release.
Every site that I've seen so far that mentions the Challenge points to a singe website that is a bit difficult to navigate.
