Conclusion 
Average Bench 80.8%
Average Bench 52%

The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 CPUPro]

Have had this CPU for over 5 years now and it's handled most of my gaming demands but really struggled on current gen games. With my new GTX1080, it's a clear bottleneck that needs replacing. [Dec '17 Kevster5]

 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.
