Horrible article. I read that it's 80% faster, get click-baited only to read further that's only in highly specific test. It does reduce credibility of notebookcheck.
The AMD Ryzen 5 9600X has been benchmarked in AIDA64, where it performs ~80% faster than its predecessor. The silicon was also spotted running at 5.8 GHz, which is well over its advertised boost clock of 5.5 GHz.
