Conclusion 
Average Bench 78.9%
Average Bench 62.1%

The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 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.
