The previous rumor/leak about Zen5's performance that I remember was from last year and claimed 10-15% IPC increase based on some internal slides from AMD, but the source was Moore's Law is Dead:

We'll see how it performs in the end and how much of that increased performance comes because of IPC improvements and how much from running at higher frequencies.
The latest leak is about some engineering samples, with a 6-core one having a 105W TDP, same as the current 7600X, and an 8-core part with a 170W TDP, a noticeable increase from the 105W of the 7700X and matching that of the higher-end 7950X and 7900X parts. But they are engineering samples, and so not entirely reliable.
Please excuse my bad English.
