The gains are smallest in general-application suites like PCMark 7 and larger in CPU-intensive programs like Photoshop CS6, the rendering program POV-RAY, and the 3D rendering test, Cinebench 11.5.

Futuremark 3DMark has three primary benchmark tests that you can run and which test you should be running depends on the system that you are benchmarking on.

If you look closer at the results for Cloud Gate you'll see that AMD won in the graphics tests, but lost in the Physics test, so Futuremark 3DMark must have more weight on the physics test than the GPU test in this test scenario.

Yeah for the life of me I can't get mine past 4.2 ghz. h100i, maximus VI hero mobo, the whole 9 yards. Stuck at 4.2 from a bad CPU roll.
omg ! instead of buying another 760 and make sli he bought i7-4790k instead of i7-4770k wtf ! you won't c more than 5 fps dif and u can oc the 4770k one to the 4790k one performance but another 760 you will get like 100 fps in bf4 btw 760 is cheaper than i7-4790k .
Im sorry dude but you piss the things off... What are talking about? The i7 4770k is a powerfull cpu too, you wont probaply notice a BIG difference between them.The 0.5ghz more make you notice this BIG difference or your mind? The i7 4790 has only 0.5 difference ghz and turbo clock speed...witch with overclocking can reach almost easly an i7 4770k. Aaaaand.... some temperatures improvements. Also is a big waste of money to jump from i7 4770k to i7 4790k ....with this money you can upgrade gtx 760 witch is your weak point in your system...not an i7 witch you aready have.....lol man.
Yeah Maybe its a glitch from cpuboss and had the 4790K for a week so far. Bought it on Amazon from this special discount page : http://amzn.to/1rjJGIY To put it in perspective for people who say it isn't worth the upgrade over the i7 4770k. I previously had a 4770k, and it was a terrible overclocker. No matter what I did I couldn't achieve a speed over 4.2ghz. Not the fault of Intel, that's just the way it is with computer components. I was going to wait until Maxwell, at the very earliest, to upgrade again, then Intel released this CPU for pretty much the same cost as the 4770k. I ended up selling my 4770k for about 30 dollars less than what I paid for, and boy I am glad I did. As we sit right now I have my 4790k at what I consider a rock solid stable 4.9ghz at 1.37v. That is completely worth the 30 dollars I paid out of pocket for this CPU. And for those of you who are wondering, this CPU is compatible with some z87 boards. The advertisement up there that says a z97 is required is a lie. So for those of you who have crappy 4770k's this CPU is worth looking into. Hope this helps someone who're looking to upgrade their gaming/video editing rig.
The new 4790k absolutely rocks the my computer with its high performance. I upgraded from a 4770k and noticed a big difference. 60 fps solid in BF4 and 3 with a GTX 760. Crysis 3 at its maximum settings with MSAA 16x and still managed a nice 45-50 fps. That is not all, though. I squeezed the absolute performance out of it. With a seidon 120m as the cooler I managed to get stable at 5 Ghz with max temps of about 80 degrees Celsius. I am very very very happy with this cpu. Thank you Intel!!!!!!
Why does the 4790K have less features (Instruction-set-extensions) in the list? According to CPU-World they have the same features, according to Intel's CPU comparison there are some new features in 4790K, though most of those (older ones) mentioned here aren't listed in Intel's comparison. So, is this an error on cpuboss' side?
Having built my own computers for years now, it is great to see that now there are affordable coolers like this one - http://www.amazon.com/dp/B0028Y4S9K/?&tag=568-20&ie=UTF8 that cool just as well or even better than some of the more expensive systems out on the market for a much cheaper price...
Also the 5.5 ghz you are referring to on air was on a air cooler but they were using the cold liquid nitrogen vapor to go into the air cooler. So unless you plan on having freezing cold air 24/7 dont expect to achieve that.
Actually, you're both wrong. http://www.hardocp.com/article/2014/06/09/intel_devils_canyon_good_bad_ugly#.U5nygWcU-Uk "Truth is, it's (5GHz) only possible on few samples and that the CPUs will throttle if used with air coolers at the voltages needed to get to the desktop. On average, the TIM change and extra decoupling on the rear of the CPUs has resulted in around 200MHz headroom over first gen Haswell in our testing so far. From information shared with me currently I would expect no more than ~5% of Devil's Canyon processors to reach 5GHz, and that would be on water cooling. Judging from these first engineering samples, 5GHz fully stable and not throttling on air seems to be unobtainable. Consider most of your 5GHz hopes dashed."
The 4790K can hit 5.5 GHz on air, and go to 6.33 GHz on LN2, so CPUBoss is definitely wrong here.
Some of these are wrong. You can get to 4.8Ghz with a water cooler and get amazing low temps with 4790k. It performers 35% faster than a 4770k at 5GHz. I got an early review copy for my YouTube channel, and I find these need to be fixed. You are giving wrong info. When comparing just stick to giving Specs of the CPU. Not opinions.
