Download the Corona CPU Benchmark. It’s easy to use: save, extract, and run the file. Benchmark starts to render the testing scene automatically and shows the result at the end, with an option to submit the result.

The tool itself is very easy to use, simply save, extract, and run the downloadable file from their site and you can get started.The benchmark itself starts automatically once you run it and it will render it's standard testing scene automatically give us results at the end that we can then use to compare performance between CPUs.

Looking at the user submitted scores on the Corona Renderer website the benchmark has been used in workstation grade systems with up to 72 CPU threads, meaning that this benchmark is made with heavy hyper threading in mind, making it suitable for testing CPUs with both small and large CPU core counts. 

We have a forum thread open on this benchmark right here where you can share your results.
