Directly proportionate to power consumption is what ASHRAE refers to as the “degree of cooling difficulty” (the inverse of thermal resistance). The degree of data center cooling difficulty rose relatively modestly during the single-core era and was basically flat during the multi-core era. But since 2018, cooling difficulty intensified dramatically—this is the Power Wars era. According to ASHRAE, “With multicore parts reaching performance limits, the only option for increased performance is increased power.”

Gone are the days where increased performance came without increasing power demand. Now, more computation requires more watts. These power wars are driven by the increasingly widespread adoption of power-intensive workloads, which is driven by exponentially rising demand for more data, real-time data consumption, and real-time analytics—particularly as organizations embrace Artificial Intelligence (AI) and Machine Learning (ML) for an increasingly wide range of applications.
