Conclusion 
Average Bench 84.2%
Average Bench 62.1%

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The Intel Core i5-4460 is a slightly upgraded version of Intel's 2013 Haswell i5-4440. Comparing the i5-4460 and i5-4440 shows that the only change is an increase in both base and turbo frequencies from 3.4 to 3.5 GHz. In terms of effective speed the 4460 is exactly on a par with the average of the top ten user rated CPUs, not a bad result for an i5. Thanks to its four cores the 4460 is can easily deal with the vast majority of desktop computing (email, web browsing, word processing etc.). In fact this model is probably overpowered for the majority of users. Most users wont require the multi-core capabilities that the 4460 offers and will do better to choose a lower powered and cheaper CPU. [Jun '14 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.
