Core i7-7660U vs Engineering Sample 506E8 3GHz
Description
Both models i7-7660U and 506E8 3GHz are based on Kaby Lake architecture.
The first Kaby Lake CPU was released in August 2016. It uses a 14 nm process and was the first architecture in breaking the previous tick-tock model. Actually, it is not that different from the preceding Skylake: it has 64kB of L1 cache and 256kB L2 cache per core.
Using the multithread performance as a reference, the i7-7660U gets a score of 132.8 k points while the 506E8 3GHz gets 210.9 k points.
Summarizing, the 506E8 3GHz is 1.6 times faster than the i7-7660U. 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.
