Civilization VI AI Test
This Civilization VI test mesures AI performance in a turn-based scenario and tends to prize per-core performance. The 3900X doesn't benefit from the auto-overclocking features, and the 3700X again suffers a slight decline in performance, indicating there are still a few kinks to work out. In either case, both processors at stock settings easily beat their previous-gen predecessors, even when they're overclocked.

Tthe Warhammer 40,000 benchmark responds well to threading, but it's clear that Intel's per-core performance advantage has a big impact.
