It varies. Performance settings slightly affect cinebench ratings due to the transition time in balanced mode. This effect likely shows up in games as well, though some may struggle with it. I believe performance mode might offer small improvements in frame timing.
Normal operation at reduced power with some cores supporting is typical for the 3300x. Issues arise when high voltage occurs under heavy load or current, which should be noted during operation.
