According to Inner Mongolia Daily, China Mobile has completed a phase of expansion for its intelligent computing center located in Hohhot, Inner Mongolia province. The project involved the construction of buildings B25 and B27 at the China Mobile data center in the New Horinger Zone. The construction was carried out by China Construction Third Engineering Bureau and covered an area of approximately 44,500 square meters, providing a total IT capacity of 120 MW.
After the expanded complex is commissioned, the facility's total computing power will reach 20,100 PFLOPS, of which 16,700 PFLOPS is dedicated to artificial intelligence-related intelligent computing tasks. The report did not specify the numerical precision of these figures. Approximately 90% of this capacity is oriented towards serving the Beijing-Tianjin-Hebei region, while 88% of the energy supply comes from green electricity.
The campus in Hohhot is part of the national program 'Eastern Data, Western Computing,' which aims to shift computational loads from energy-intensive eastern cities to western regions where cheaper renewable energy is available. It serves as a key node in China Mobile's 4+N+31+X computing network and a center within the national integrated computing network. According to Securities Times, the one-way latency between Hohhot and Beijing via a 400G OTN backbone is 3.5 milliseconds, meeting the requirements of latency-sensitive corporate clients in the Beijing area.
The intelligent computing center in Hohhot is positioned as the world's largest center of its kind managed by a telecommunications operator on a single site. Before this expansion, it began operations in December 2025, housing approximately 20,000 AI accelerators, with over 85% of its AI chips manufactured domestically. The publication IT Home specifically points to the scale of AI in the Hohhot node, featuring 19,000 cards built using heterogeneous computing, GPU pooling, and cold plate liquid cooling.
The cooling system and power supply are another advantage of this facility. Thanks to large-scale cold plate liquid cooling and an AI energy management system, the average energy efficiency has been reduced to 1.15. In 2025, the center acquired 750 million kWh of green energy through direct procurement and long-term contracts, which allowed it to reduce carbon emissions by 370,000 tons. The New Horinger Zone is located in the center of Inner Mongolia's wind and solar base, which is one of the largest in China. Furthermore, China Mobile operates what it calls the largest cluster intelligent computing center for operators in Harbin.
