Conclusion 
Average Bench 60.8%
Average Bench 75.8%

The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics. [Jan '17 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
