Benchmarks for choosing the right CPU Is there any reliable benchmark resource (website?) for choosing the right CPU for Blender? I found http://blenchmark.com/cpu-benchmarks, but they seem not reliable. For example, according to them, AMD's Ryzen 1700 is even faster than Intel Core i7 7820X, which seems unreal.

How do you choose the right CPU or get insights regarding Blender performance of different CPUs?
There are several standard blend files provided by the Blender Foundtation for testing and benchmark purposes available at Demo Files. The BMW scene as become a common test scene for various purposes.

In recent years due to the popularity and it has become an informal benchmark tool used by hardware manufacturers to provide a common ground for comparison. This has the advantage of using real world computational needs rather than artificial benchmark tools created for the sole purpose of testing

As such the Blender foundation has started a new initiative to provide an official reliable benchmarking tool for testing purposes.

This has materialized as a website called Blender Open Data that aims to collect performance data for various hardware configurations.

As of November 2018 status is still in beta testing, so not much information is available at the moment.
