Conclusion 
Average Bench 72.4%
Average Bench 55.1%

The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]

The Intel Core i3-4160 is a dual-core four threaded 4th generation (Haswell) processor. It was released in Q3 2014 and scores a respectable 91 for effective speed. With its base frequency of 3.6 GHz, the 4160 is fast enough to run the vast majority of applications smoothly and it’s very reasonably priced for its performance which make it a sensible choice even when considering building a gaming PC. Although the integrated Intel HD Graphics 4400 are absolutely fine for general desktop use such as web browsing and word processing they may bottleneck a gaming machine. A 20% price premium would buy the slightly older i3-4350 which has a 33% larger (4MB) cache but its only about 1% faster (full comparison here). Overall the i3-4160 represents the best value for money I have seen outside Intel's Pentium and Celeron range of CPUs. [Nov '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.
