It's difficult to get a sense of scale from four comparison points. However, if we were to add, say, AMD's Kaveri-based A10-7850K to the chart, you'd see a workload completion time in 3ds Max 2012 of 3:46. That's 1:45 longer than a stock Core i7-4790K. In the context of our battle between Haswell-based processors, though, the biggest benefit again comes from overclocking the stock Core i7-4770K. Of course, a stock 4790K is just a bit quicker, and applying some extra clock rate to the new CPU helps even more.
For the sake of comparison, a Core i7-4790K, overclocked, is almost as fast as a Core i7-3930K at its default clock rate in this well-threaded application.
Expect steady improvements as you step from Core i7-4770K at its factory frequencies to the same CPU overclocked to a Core i7-4790K. Blender easily taxes all four cores on both processors, so the overclocked chips are operating at 4.2 and 4.4 GHz, respectively.
Vegas Pro 12 is set up to exploit our GeForce GTX Titan through OpenCL. Despite the fact that we're offloading some of the host processing workload, CPU performance does still matter, as only some of the rendering process is accelerated.

bring back solder intel.
I built my PC at the end of last year, beginning of this one and went with a i7-4930k. I really wanted a six core processor and have not been disappointed. I have been itching to build another PC because it was really fun to put the plan of components together and although my hands were to big and my medical conditions prevented me from getting to do a lot of the building, my wife helped a lot with that part and it was nice to see the finished product in action. With that being said, I don't have a lot of money for anything right now and hope that my disability pay finally comes through so I can start picking together parts for a computer for my wife. She won't need anything as powerful as I have, and the i7-4790k sounds pretty sweet.
On a side note, this website annoys me. I click to add comment and the default fields are for signing up, no logging in, and when I do, I am back to the homepage. Great.

Second problem: Why is Tom's using 1.275 V for 4200MHz on both units? Is that actually 1.275v with LLC disabled or is LLC on a setting resulting in the lowest load voltage? If one of those units need 1.275v to be stable at 4200 you have a real donkey sample on your hands. Even the worst i7-4770k are stable at 1.20v @ 4200. Or was the over voltage designed to test an unrealistic incompetent situation to either emphasize or DE-emphasize the TIM difference?
Voltage wall is still at the approximate same place. Heat is still the limiting factor. I expect some of the better binned 4670K will hit equal or better than the 4690K.
I'll stay with my 3570K @ 4.3ghz - this clearly isn't much of a step up. Looks like I'm waiting for a DDR4 system in a couple years.
Not impressed.
My interest lies in, will the devils canyon i5 4690k be able to hit the same clocks and temperatures as the i7 4790k at the same voltages, or for the i7 is there just a more extensive binning process or something of the sort? Your comment at the beginning of the article when discussing these realistic and sustainable overclocks really hit home in relation to this.
The point of running both CPUs at the same voltage and the same clock rate is measuring the difference of the TIM. For the rest of the tests, each chip is pushed as fast as it'll go, stably.
So why would you go out of your way to compare Devil's Canyon to the A10-7850K ??
Still, even though the performance is another step faster than AMD, for my purposes the cost is still a bit high. Still, I'd love to see what it can do at 5.0 GHz.
