Core i7-4790K Review: Devil's Canyon Tantalizes Enthusiasts

By published

Despite a clear performance advantage, Intel just doesn't seem like an enthusiast-friendly company. Certain elements in the organization want to change that perception, though. Devil's Canyon is meant to allay power users with more speed.

Every test we've run thus far is optimized for multi-core processors, which means more often than not, power users who run these titles are going to want six-core Ivy Bridge-E-based platforms when budget allows. You'll still get excellent performance from an overclocked Core i7-4790K though. The improvement going from stock Core i7-4770K to tuned -4790K is more than 14 percent.

After Effects is also threaded, though the workload we throw at it already finishes so quickly on a Core i7-4770K that there's not a ton of room for improvement. As a percentage, you can still expect a roughly 13 percent speed-up going from stock 4770K to overclocked 4790K.

As you no doubt already know, we run two Photoshop benchmarks. The first consists of filters optimized for multi-core CPUs. The second employs filters that exploit graphics processing through OpenCL. In both cases, Intel's Devil's Canyon serves up quantifiable benefits.

    Really nice read. I am very excited to see how well the i7-4790k performed, and that means in 2-3 years the CPUs that will be out are going to be amazing. It will be nice to start seeing stock clocked 4 GHz to 4.5 GHz Intel CPUs to better keep up with the AMD overclocking that many builders do. I prefer Intel and really feel that they offer the best performance for their CPUs.

    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.

    The average overclock based upon my Google Doc of about 185 overclocks now averages at 4.55ghz for Haswell. A tim change isn't going to gain an extra 200mhz and even then, it's being generous.

    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.

    It would've been nice to show benchmarks and temps vs sandy bridge (2600K) at same frequency to help us gauge the progress (or the lack of) that's been made in the last three and a half years.

    so one of their biggest selling points ended up resulting in a 6 degree difference.

    bring back solder intel.

    Seriously u should bench it against the old Hex core like 990X, 3930K, 4930K.

    nice improve :) please where i put my razor? no way 6ºc improve. my ambient temp hits 45ºc my old 3770k 4.6ghz hit 88ºc on core. with this "new shinning old tech" i can't hit the 4.2ghz. intel miss and miss Hard!

    I think that the whole real point of releasing this new processor and the others to follow it is simple. Intel wants to offer a better stock clock for those that do not want to or do not know how to overclock their processor. And since AMD allows easier overclocking, or at least a whole lot more processors that can be overclocked than the ones that Intel specifies for their own products. This will help a lot of consumers decide Intel over AMD if they continue to offer comparative clocks.

    First problem: 6C between the old and new TIM is something, but not much. As one of the big improvement features, that is disappointing.

    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?

    Sorry, but I'm entirely unimpressed. Improved TIM is a waste of time. I thought this was going to release with fluxless solder. 6° worth the wait ? 6° is the difference between air cooling and water cooling.

    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.
