Pandaily reported on 12 October that China Mobile had completed an expansion of its Hohhot computing centre that will bring the site to 20,100 PFLOPS once operational, including 16,700 PFLOPS for AI workloads. Buildings B25 and B27 add 120 MW of IT power and cover about 44,500 square metres.
About 90% of the capacity is intended to serve the Beijing-Tianjin-Hebei region. The Hohhot campus is part of China’s Eastern Data, Western Computing programme, which shifts computing workloads from eastern cities to western regions with cheaper renewable energy. A 400G OTN connection between Hohhot and Beijing has one-way latency of 3.5 milliseconds.
The centre entered production in December 2025 with roughly 20,000 AI accelerator cards. IT Home put the Hohhot node’s AI scale at 19,000 cards, according to Pandaily. More than 85% of the centre’s AI chips are domestically made. Green electricity accounts for 88% of its supply, and its average power usage effectiveness is 1.15.
The centre secured 750 million kWh of renewable electricity in 2025 via direct provision and medium- to long-term agreements, with a reduction of 370,000 tonnes in carbon dioxide emissions.
