Core i5-6600K vs i7-6700
Description
Both models i5-6600K and i7-6700 are based on Skylake architecture.
Sky Lake is also known as 6th generation Core. Include Thunderbolt 3.0, SATA Express and Iris Pro graphics with DirectX 12. It uses LGA 1151 socket for mainstream models and LGA 2066 for X-Series. Sky Lake comes with AVX2 support in all mainstreams CPUs and AVX-512 in some high end models.
Using the multithread performance as a reference, the i5-6600K gets a score of 199.9 k points while the i7-6700 gets 243.4 k points.
Summarizing, the i7-6700 is 1.2 times faster than the i5-6600K . To get a proper comparison between both models, take a look to the data shown below.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.
Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.
If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
