For those confused about the single-thread performance improvement in PassMark, keep in mind that AMD had worked directly with PassMark to identify a performance deficit with Zen 2 which was related to a Windows 10 update and the new version of PassMark released early this year. Thus AMD had access to source code to identify the issue. The solution was for PassMark to change the PRNG (pseudo random number generator) in order to divorce undocumented Windows 10 code from creating a problem. Subsequently a new version of PassMark was released that was more favorable to AMD. I made a point to David over at PassMark that both the old and new PRNGs used actually are not very good in terms of randomness and performance.
Therefore, it is not inconceivable that AMD used knowledge of PassMark to improve Zen 3, but modifications would have had to occur within the last 6 months. However, decent improvements are trickling out in other benchmarks, which would make the case that Zen 3 is simply better under all circumstances. Whether or not PassMark is truly an exaggerated case, based on the limited data so far, remains to be seen.
