This tutorial focuses on 7zip to benchmark your CPU. It is free to download and has an implemented benchmark mode.

The download can be found here: https://www.7-zip.org/download.html

How it works:
Simply launch it after download and installation and hit the "Tools" category. Then select "Benchmark". Your system will immediately be stressed out in calculation of a 32 MB dictionary. It is compressed and decompressed. Compression with LZMA method and Decompression with LZMA method is executed. The result of the 7zip benchmark is measured in million instructions per second.

You can choose a different dictionary size, although 32 MB is the standard when it comes to comparing CPU performance.

In addition to that you can select how many threads of your CPU should be used during the benchmark. By default, the maximum number of threads is selected.

Below you can see the CPU Usage in %. On 8 threads a percentage of 720 means that all 8 threads are being used by about 90% on average. The Rating is then used to compare your CPUs performance.

Note by the developer: Compression speed and rating strongly depend on memory (RAM) latency.
Decompression speed and rating strongly depend on CPU integer operations.

So keep that in mind if the same CPU performs better/worse than yours.
