Meta Cheyenne is an AI Data Center under construction, projected to host an estimated 251k H100-equivalent chips — supported by 220 MW — at a capital cost of $8.3 B. The timeline of IT power and compute capacity is based on satellite imagery, our cooling equipment power model, structural similarity to known buildings, chip availability, and chip efficiency. Announced in July 2024, Cheyenne will be Meta’s 21st data center in the U.S.
