Zen 2 is very good in number crunching and synthetics. But it has a problem - terrible memory latency. 70ns with 3600cl16. (https://www.userbenchmark.com/UserRun/18168279) It distills to a not-so-good gaming frame times. It's 64mb L3 cache (https://en.wikichip.org/wiki/amd/ryzen_9/3900x) helps only partially.

Few games will suffer greatly from it, but there are several titles with RAM bottlenecks, like PUBG and FarCry.

Anyway, AMD has a much better price/performance offer than Intel. For general puprose Intel is totaly anihilated, but for the games they are still more than competitive.
