What Is an AI Data Center?

An AI data center is a facility designed around dense racks of accelerators rather than general-purpose servers.

Three differences dominate. First, power density: traditional racks were designed for a few kilowatts, while AI racks can require tens of kilowatts or more. Second, cooling: at those densities air cooling reaches its limits, so liquid cooling moves from exotic to standard. Third, networking: training clusters need very high bandwidth and very low latency between every GPU, which changes the physical layout of the building.

The practical consequence is that site selection is driven by grid connection timelines, water and cooling options, and the ability to deliver power in large blocks. Land is rarely the constraint; electricity and equipment lead times usually are.
