It's because the internal graphic is weaker in the i7. Use a dedicated GPU and i5-6600k will have lower TDP.

No i7 with 22nm has lower power consumption check above
The benchmark comparison is rigged as fvck, I don't care what numbers cpuboss wanna draw for the 6600K, it is no match for the 4770K, nuff said... All that "current model is better", 14nm process cosmetic comparison reasons to consider to buy the 6600K don't mean shlt when it comes to results.
The i5 is no match for the i7. You can't compare them - they are completely different cpus. Mind you, the 6600k is 6th gen and the best i5. Even then, it doesn't match the cpu. How does cpuboss test the cpus? Is it frames? Benchmark? Or is it stress tests. In terms of "performance" what does that suggest? If you want to see me installing a cpu visit my channel. I'll be uploading soon.
You shouldn't be disappointing, they aren't going for raw performance right now, because they really have no competition in the high end. But the 6600k has much better thermals and lower power consumption, because of it's smaller manufacturing node.
Not much difference between the two, but the 4770 has hyperthreading and more L3 cache. I'm disappointed by both Broadwell and Skylake's lack of improvement over Haswell (in terms of performance).
Wow really ? The i5 6600K is no match for the i7 4770K there is now way they have the same score.
