ASICs are also populated onto cards, and miner firmware handles tuning the hash rate of each chip (or card) based on inputs like desired temperature and power consumption. These inputs are often adjustable. Heat causes chips and other components to degrade, so not everyone runs their miners at maximum output all the time.
