But the stock clock on the 4790k is 4 GHz with a turbo boost up to 4.4 GHz - significantly higher than the 4790 @ 3.6/4 (by 22%). So if even if you don't overclock, the k is a better choice.

Nah, 400MHz won't even be noticeable. I overclock more than that and see no performance boost in anything.

No it doesn't. Where in the world did you get that?

Haswell refresh = slightly better binning of the Haswell to get 100 MHz more.

4790k and 4690k = Devil's Canyon = better Thermal interface material between the die and Integrated heat spreader, + Integrated voltage regulatar parts more spread out on the die in order to better dissipate heat, + better front end capacitors to smooth out input voltage.

They ALL use the on-die integrated VRM just like the original Haswell.

The Devil's Canyon has better thermal properties and is binned for higher frequency.

22% is noticeable otherwise why overclock at all? And this isn't an overclock, it is basically for free so why would you even consider choosing a process that performs less by 22%?

EDIT: Sorry about 12%, but the argument is the same.

The Haswell refresh (4790 and 4690) did absolutely nothing to address the heat issues with the Haswell.

The Devils Canyon (4790k and 4690k) are attempts at addressing the issues as I mentioned in a previous post.

Yeah the argument is the same, so are the results, no performance gain. We've checked and rechecked in file transfers, video encoding, in-game FPS, etc. A CPU overclock, or turbo boost, or however it runs faster, doesn't help these things. By "we", I mean in the overclocking forums here.

Boosting the GPU frequency can help video related tasks though.

For games sure, but we are not talking about games here, right? We are talking about video editing, that utilizes the CPU and is not graphics bound, so that CPU boost will be a direct benefit.

And get your information right about the recent Intel releases.

I mucked that up. I was thinking about this thread when the Newegg ad came in email and for some reason I saw a K that was not there. The 4790 has been out for a while now.

You didn't muck anything up. Intel releases, their purpose, and their naming are all pretty mucked up
