Benchmarks: data-compression and -encryption
We run five data-compression and –encryption benchmarks. First we compress 2GB of data using both 7Zip as well as Winrar. We also run three parts of the AIDA64 benchmark. Zlib is a popular compression method that is used by a lot of software. AES is one of the most used encryption algorithms and is, for example, the basis for the SSL-encryption of HTTPS-websites. With AIDA64 we also measure how fast data can be hashed.
The new processors are a lot faster than existing models in 7Zip. WinRAR is multi-threaded to a certain extent, and the relatively high clock frequencies mean that the scores are better than those of the 7700K and 7600K here. In the AIDA compression test the Core i5 8400 manages to keep up with the top model of the previous generation. The 8700K performs even better, but cannot compete with the 1700X and other high end Ryzen processors in this test. With the AIDA AES and Hash benchmarks Coffee Lake definitely outperforms Kaby Lake, but AMD's Ryzen remains the leader in this specific benchmark.
